Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2

The NM_003837.4(FBP2):c.830G>A(p.Arg277Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000156 in 1,609,680 control chromosomes in the GnomAD database, including 2 homozygotes. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R277W) has been classified as Uncertain significance.
