LRATD2

Chr 8

LRAT domain containing 2

Also known as: BCMP101, FAM84B, NSE2

LRATD2 encodes a protein localized to the cytoplasm and plasma membrane, though its specific molecular function remains unclear. The gene shows very high constraint against loss-of-function variants (pLI = 0.0004), suggesting that biallelic mutations would likely cause severe developmental disorders, but no definitive disease associations have been established yet. This represents a candidate gene where pathogenic variants may cause as-yet-uncharacterized pediatric neurological or developmental phenotypes.

The highest-scoring mechanism for this gene is gain-of-function.

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.
