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]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.84
• PP5: Variant 19-16904267-A-G is Pathogenic according to our data. Variant chr19-16904267-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 375309.Status of the report is no_assertion_criteria_provided, 0 stars.
