LRRC14B

Chr 5

leucine rich repeat containing 14B

This gene encodes a leucine-rich repeat containing protein that is a member of the PRAME family. Mutations cause autosomal recessive primary microcephaly with simplified gyral pattern, intellectual disability, and seizures, typically presenting in infancy. The gene shows minimal constraint against loss-of-function variants, which is consistent with the recessive inheritance pattern observed in affected individuals.

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

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.
