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.2053A>T (p.M685L) alteration is located in exon 11 (coding exon 11) of the CDH22 gene. This alteration results from a A to T substitution at nucleotide position 2053, causing the methionine (M) at amino acid position 685 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
