OVCH1 (ovochymase 1) is a gene located on chromosome 12 whose function remains incompletely characterized, though recent evidence suggests involvement in immune and inflammatory processes. An intronic OVCH1 variant (rs10492374) was identified as a novel susceptibility locus for HLA-B*08:01-positive early-onset myasthenia gravis (EOMG), with heterozygous carriers showing increased OVCH1 gene expression 1. The gene's antisense RNA, OVCH1-AS1, shows differential expression patterns across multiple pathophysiological contexts. In Turner syndrome (monosomy X), OVCH1-AS1 expression is consistently elevated across fetal tissues and placenta, suggesting a potential compensatory response to X chromosome 12 2. OVCH1-AS1 is also differentially expressed between frail and non-frail older adults, with implications for age-related loss of homeostasis and frailty development 3. Additionally, OVCH1-AS1 functions as a disulfidptosis-related long noncoding RNA with prognostic significance in kidney renal clear cell carcinoma, where it contributes to a biomarker signature predicting patient outcomes and immunotherapy response 4. A rare OVCH1 variant was identified in familial Ménière's disease, though the specific pathogenic mechanism remains unclear 5. These findings suggest OVCH1 and its antisense transcript participate in immune regulation, age-related pathology, and cancer progression, though direct protein function requires further investigation.
