Seeking Insights on My Nephew's ERF Gene Mutation and Its Implications
Hello esteemed medical professionals, I am reaching out concerning my 10-year-old nephew, who has recently had an ExomePlus genetic test conducted. The test results indicated the presence of a heterozygous pathogenic variant in the ERF gene (specifically chr19:42753062_42753063delTT, c.1201_1202delAA, p.Lys401GlufsTer10). This mutation is associated with Chitayat Syndrome and interstitial lung disease (ILD). Important Details: - Patient Age: 10 years, Male - Clinical Observations: Experiences breathlessness during physical activities, exhibits failure to thrive, has a reduced appetite, and has been diagnosed with interstitial lung disease (ILD) confirmed by CT imaging. - Genetic Mutation: Detected in the ERF gene, categorized as heterozygous, pathogenic, and inherited in a dominant fashion. - Family Medical History: No comparable incidents in relatives. - Additional Genetic Findings: No other significant anomalies were detected in mitochondrial DNA or copy number variations (CNVs). - Test Quality: The test exhibited a high level of reliability and sequencing precision. In light of this information, I have several inquiries: 1. Are there established treatments or interventions for disorders related to the ERF mutation, specifically Chitayat Syndrome? 2. Is it possible to manage or slow down the progression of ILD in pediatric patients using medications such as corticosteroids or immunosuppressants? 3. What does the long-term outlook look like for children with ERF mutations who currently exhibit mild symptoms? 4. Are there any research institutions or experts globally that are investigating this particular gene or associated syndrome? 5. What routine care or ongoing monitoring should be recommended for patients identified with such genetic variations? We have initiated consultations with specialists in the field; however, any guidance or expert opinions regarding the next steps would be immensely appreciated. Thank you for your attention and assistance. 🙏

Could Rapid Healing Indicate an Underlying Issue?
It's commonly advised to inform your physician if your healing process seems slower than expected, as that may indicate a potential health concern. But is it possible to heal at an accelerated pace, and could this be a cause for alarm? To illustrate, about a month prior, I experienced a significant tumble down some stairs, resulting in a severe bruise on my leg. By that evening, the bruise had expanded to a size larger than my palm and had taken on a deep purple hue. The following morning, it appeared nearly black—definitely the most intense bruise I'd ever encountered. Yet, remarkably, just four days later, it had almost vanished entirely, leaving only a few yellow spots smaller than my fingernail. Although I’ve always been a relatively fast healer, I typically expect bruises to linger for a minimum of two weeks. I’ve been struggling with debilitating fatigue, frequent nausea, vomiting, night sweats, and hip discomfort for some time. Recently, my nausea has intensified to the point where I can barely manage to consume more than a couple of crackers, which has unfortunately led to some weight loss. After some investigation, including an MRI of my hip—which appeared normal—I was advised by an orthopedic specialist to pursue physical therapy since the hip pain, my first symptom, has persisted since January (and the MRI took place in April). I have a scheduled appointment with my general practitioner, and I am hopeful to receive clarity on my situation. When my partner made a light-hearted comment about my rapid bruise recovery as a good sign, suggesting it ruled out leukaemia, it sparked my curiosity about whether accelerated healing could be linked to any underlying health issues that might be contributing to my current ailments.
Experiencing Persistent Nerve Pain After ABG Procedure
Age: 22, Weight: 61 kg, Height: 165 cm Greetings, fellow Redditors, particularly those in the medical field. I'm feeling quite distressed as I struggle with an inability to fully extend my left arm due to ongoing nerve pain, which presents itself like an electric shock each time I try to move it. This issue arose after I was hospitalized for dehydration, during which a nurse inadvertently impacted a nerve while performing an arterial blood gas (ABG) test. The sensation was excruciating and left me quite shaken. I’m deeply concerned about the possibility of lasting damage, as it has significantly hindered my daily activities. Being a nurse myself, this raises worries about my ability to perform my job effectively. Is this experience common? How long is the recovery period? Am I at risk of never returning to normal function? Any guidance would be greatly appreciated. 🥺
Understanding Trace Hematuria: A Personal Account
Subject Information: 21-year-old male, standing at 5 feet 5 inches tall and weighing 187 pounds. Hello! A couple of weeks back, I underwent a flight physical, during which a urine dipstick test revealed the presence of blood, albeit in a minimal amount. I had done some abdominal exercises the previous night, so I initially thought that might explain the result. However, fast forward a few weeks to the 24th, and during my annual check-up—after another night of working my abs—I encountered a similar issue; they detected trace blood in my urine once more. With that, I had another urine test along with some bloodwork, and thankfully, my doctor informed me that everything came back normal. Despite this reassurance, she did refer me to a urologist for further evaluation. Should I be concerned about this? It does make me a bit anxious, to be honest. If it would assist, I’m happy to share the results of my lab tests.
Discomfort in My Left Heel
Greetings. I am a 21-year-old male, standing at 6 feet 1 inch and weighing 201 pounds. I identify as Caucasian. While I occasionally consume alcohol and vape, I do not smoke or engage in any other substances. In recent months, my physical activity has significantly declined due to my preparations for the MCAT. I've been experiencing a notable discomfort in my left heel during walking. The sensation intensifies when I go barefoot and is particularly acute on hardwood floors. Though the pain does not prevent me from walking, each step induces a wince of discomfort. It's important to mention that this pain is most pronounced in the morning upon waking and also flares up when I rise after periods of sitting or inactivity. Recently, I've incorporated jogging into my routine, which is a change from my previous habits. As for my diet, I have switched to one with lower fat content and increased fiber. My latest blood work revealed that my LDL cholesterol levels are slightly elevated for someone my age. I seek your guidance regarding this issue. It appears to align with plantar fasciitis symptoms, but I'm uncertain if there might be another underlying cause. Additionally, to provide more clarity, the discomfort seems localized around the calcaneus, particularly near the heel spur, which raises my doubt about the diagnosis being exclusively plantar fasciitis. Thank you!
Chronic Health Challenges with Uncertain Origins
Hello everyone. I've been grappling with ongoing health issues for an extended period. My symptoms include relentless fatigue, muscle weakness, noticeable weight loss, sporadic severe aches throughout my body, heaviness in my limbs upon waking, intermittent swelling of a lymph node near my ear, an increase in cherry angiomas alongside freckles, heightened appetite, disrupted sleep accompanied by nausea, and heavy menstrual cycles with clots. Additionally, I experience frequent pressure-like headaches, occasional small bruises on my legs, and an unusually high number of colds—six this year alone. These complaints have persisted since November 2024. In February, my low ferritin levels were revealed, dropping to just 20, coinciding with extreme fatigue, muscle weakness, heart palpitations, hair loss, difficulty breathing, and abnormal gastrointestinal issues such as bloating, erratic fatty stools, and poorly digested food. My healthcare providers have dismissed my low ferritin, believing it to be insignificant because my iron panel and CBC results seemed normal. I focused on consuming iron-rich foods until June, but only saw a slight increase to 25. Since then, I've noticed further fat loss in my limbs and a rise in cherry angiomas and freckles. I began taking Vitron C three times weekly for five weeks in June; however, I felt particularly weak and short of breath during my menstrual cycle, and the ferritin level remained unchanged. Recently, I increased my intake to every other day, resulting in slight improvements in fatigue and muscle weakness, but I continue to experience random, transient aches in my bones—specifically in my shins, ribs, hips, and wrists. I contracted COVID in June, and since then, the lymph node behind my ear has remained swollen, with swelling now also noticeable in my groin area. My white blood cell count was alarmingly low at 3.98 before my positive test. Occasionally, I've woken up feeling damp but not completely soaked. Furthermore, I’ve been experiencing persistent low back pain since my illness and have noticed changes in my vision. My doctor described the lymph nodes as "shotty" and not a cause for concern; nonetheless, it has been seven weeks since my COVID infection, and I'm increasingly worried about their continued presence along with my other distressing symptoms. I've undergone a comprehensive range of tests since December, including CBC, CMP, B12 levels, various iron tests, cortisol, hormone evaluations, screenings for PCOS, CRP, ANA, sed rate, magnesium, phosphorus, CK, TSH and T4, vitamin D assessments, SIBO testing, celiac disease screening, stool analyses, a home sleep study, a Zio heart monitor, electrocardiograms, and transvaginal ultrasound—all of which returned normal results. I'm concerned that my issues may signify a serious condition like cancer. My physician suspects chronic fatigue syndrome but questions linger about whether it should be a diagnosis based solely on exclusion. It’s also thought I may have had COVID back in February, yet I tested negative for both that and the flu at the time. My weight has seen a minor decline, but not noteworthy enough to raise alarms. I recently requested additional tests for LDH, CRP, and Lyme disease. I'm scheduled to follow up with a gastroenterologist soon; meanwhile, I've been experimenting with probiotic drinks to help my digestive system, but I suspect I might have histamine intolerance due to experiencing flushing and internal tremors in the afternoons. Consequently, I find myself at a crossroads, unsure of the next steps to take. What do you think might be contributing to my low ferritin and the array of chronic symptoms I’m dealing with? I would greatly appreciate any insights. Thank you!
