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.

Ambry Genetics

Jun 10, 2024

The c.2088G>C (p.E696D) alteration is located in exon 11 (coding exon 11) of the CDH22 gene. This alteration results from a G to C substitution at nucleotide position 2088, causing the glutamic acid (E) at amino acid position 696 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
