Also known as: AIE-75, DFNB18, DFNB18A, NY-CO-37, NY-CO-38, PDZ-45, PDZ-73, PDZ-73/NY-CO-38
This gene encodes a scaffold protein that anchors and organizes protein complexes essential for mechanotransduction in cochlear hair cells and microvilli organization. Mutations cause autosomal recessive Usher syndrome type 1C (congenital profound deafness with prepubertal onset retinitis pigmentosa) and isolated autosomal recessive deafness. The gene is not highly constrained against loss-of-function variants, consistent with its recessive inheritance pattern.

Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
