Genetic Variant FAM76B:p.His153Leu (chr11-95783170-T-A) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_144664.5(FAM76B):c.458A>T(p.His153Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,542 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 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. H153R) has been classified as Uncertain significance.
