FAM156B
Chr Xfamily with sequence similarity 156 member B
Also known as: TMEM29B
The FAM156B protein binds methylated histones and localizes to the nuclear envelope. Mutations in this gene have not been definitively associated with any recognized pediatric neurological disorders in the current literature. The clinical significance of variants in FAM156B remains uncertain.
Population Genetics & Constraint
Constraint data not available from gnomAD.
This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function 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.
