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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 08, 2024The c.5474C>T (p.A1825V) alteration is located in exon 41 (coding exon 41) of the CPAMD8 gene. This alteration results from a C to T substitution at nucleotide position 5474, causing the alanine (A) at amino acid position 1825 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
