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.

The c.1343A>G (p.H448R) alteration is located in exon 13 (coding exon 12) of the FBF1 gene. This alteration results from a A to G substitution at nucleotide position 1343, causing the histidine (H) at amino acid position 448 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
