Genes affected
FANCB (HGNC:3583): (FA complementation group B) This gene encodes a member of the Fanconi anemia complementation group B. This protein is assembled into a nucleoprotein complex that is involved in the repair of DNA lesions. Mutations in this gene can cause chromosome instability and VACTERL syndrome with hydrocephalus.

Fanconi anemia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 10, 2017 | This variant has not been reported in the literature in individuals with FANCB-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces phenylalanine with leucine at codon 535 of the FANCB protein (p.Phe535Leu). The phenylalanine residue is moderately conserved and there is a small physicochemical difference between phenylalanine and leucine. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. - |
