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]

Submissions by phenotype

Heterotaxy, visceral, 6, autosomal Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 15, 2020This variant has not been reported in the literature in individuals with CFAP53-related conditions. This sequence change replaces serine with phenylalanine at codon 492 of the CFAP53 protein (p.Ser492Phe). The serine residue is moderately conserved and there is a large physicochemical difference between serine and phenylalanine. This variant is present in population databases (rs371913662, ExAC 0.04%). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
