Genes affected

CFAP53 (HGNC:26530): (cilia and flagella associated protein 53) This gene belongs to the CFAP53 family. It was found to be differentially expressed by the ciliated cells of frog epidermis and in skin fibroblasts from human. Mutations in this gene are associated with visceral heterotaxy-6, which implicates this gene in determination of left-right asymmetric patterning. [provided by RefSeq, Aug 2015]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 18-50261062-ACCTGAATTGCTGGTCTAGCTTTTCAGCCACAAAATCCTGCCTCTCTTTTTCATTCTTCTCTTTTAGTAATTTAGTTTTCTCTCTCATCCTATCTTTTTTCTCCTCAATGGTTTCTTTCTTCAATTGCATTTCTGTAAAATACTCATTTTCTTCTAATGCTAAAAGCTCACGTAG-A is Pathogenic according to our data.
