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.

Ambry Genetics

Mar 16, 2022

The c.723G>T (p.Q241H) alteration is located in exon 4 (coding exon 3) of the VANGL2 gene. This alteration results from a G to T substitution at nucleotide position 723, causing the glutamine (Q) at amino acid position 241 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
