Genes affected

CDH22 (HGNC:13251): (cadherin 22) This gene is a member of the cadherin superfamily. The gene product is composed of five cadherin repeat domains and a cytoplasmic tail similar to the highly conserved cytoplasmic region of classical cadherins. Expressed predominantly in the brain, this putative calcium-dependent cell adhesion protein may play an important role in morphogenesis and tissue formation in neural and non-neural cells during development and maintenance of the brain and neuroendocrine organs.

The c.2038A>G (p.T680A) alteration is located in exon 11 (coding exon 11) of the CDH22 gene. This alteration results from a A to G substitution at nucleotide position 2038, causing the threonine (T) at amino acid position 680 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
