Variant summary

Our verdict is Benign. The variant received -16 ACMG points: 0P and 16B. BP4_StrongBP6_Very_StrongBS2

The NM_001018113.3(FANCB):​c.1442G>A​(p.Arg481His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000112 in 1,197,198 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 31 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R481C) has been classified as Uncertain significance.

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.
