Genes affected

CPAMD8 (HGNC:23228): (C3 and PZP like alpha-2-macroglobulin domain containing 8) This gene encodes a member of the protease inhibitor I39 (alpha-2-macroglobulin) family of proteins. These proteins are important in innate and acquired immunity. The encoded protein is membrane-associated and proteolytically processed to generate two chains. Mutations in this gene cause a form of anterior segment dysgenesis, a developmental disorder of the eye. [provided by RefSeq, May 2017]

The c.5764G>A (p.G1922S) alteration is located in exon 42 (coding exon 42) of the CPAMD8 gene. This alteration results from a G to A substitution at nucleotide position 5764, causing the glycine (G) at amino acid position 1922 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
