WBP2

Chr 17AR

WW domain binding protein 2

Also known as: DFNB107, GRAMD6, WBP-2

WBP2 encodes a transcriptional coactivator that enhances the activity of estrogen and progesterone receptors and modulates expression of post-synaptic scaffolding proteins. Biallelic mutations cause autosomal recessive deafness (DFNB107), presumably through disruption of hormone receptor-mediated transcriptional regulation affecting auditory 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.
