NMRAL1
Chr 16NmrA like redox sensor 1
Also known as: HSCARG, SDR48A1
This gene encodes a redox sensor protein that binds NADPH and regulates cellular responses to changes in NADPH/NADP+ ratios, including modulation of nitric oxide synthesis and interferon signaling pathways. The gene is not highly constrained against loss-of-function variants based on population data (pLI < 0.9, LOEUF > 0.35), suggesting that complete loss of function may be tolerated. No established Mendelian diseases have been definitively associated with NMRAL1 mutations in current medical literature.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
