LYRM1

Chr 16

LYR motif containing 1

Also known as: A211C6.1

The protein promotes cell proliferation and inhibits apoptosis in preadipocytes, contributing to adipose tissue homeostasis. Mutations cause autosomal recessive mitochondrial complex III deficiency, presenting with severe early-onset neurodegeneration, developmental delay, and multisystem involvement. This gene is extremely intolerant to loss-of-function variants, indicating that complete protein loss is likely incompatible with normal development.

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.

GOFprediction above median

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.
