Genes affected
FBF1 (HGNC:24674): (Fas binding factor 1) Involved in apical junction assembly and establishment of epithelial cell polarity. Acts upstream of or within cilium assembly. Located in centriole; centrosome; and spindle pole. Part of ciliary transition fiber. Colocalizes with apical junction complex and keratin filament.

Submissions by phenotype

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2021This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
