Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_001018113.3(FANCB):c.1541A>G(p.His514Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. H514H) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 23, 2022 | This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 514 of the FANCB protein (p.His514Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FANCB-related conditions. ClinVar contains an entry for this variant (Variation ID: 456178). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. - |
