Genes affected

VANGL2 (HGNC:15511): (VANGL planar cell polarity protein 2) The protein encoded by this gene is a membrane protein involved in the regulation of planar cell polarity, especially in the stereociliary bundles of the cochlea. The encoded protein transmits directional signals to individual cells or groups of cells in epithelial sheets. This protein is also involved in the development of the neural plate.

The c.307T>C (p.C103R) alteration is located in exon 4 (coding exon 3) of the VANGL2 gene. This alteration results from a T to C substitution at nucleotide position 307, causing the cysteine (C) at amino acid position 103 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
