Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM5 BP4_Moderate

The NM_001375567.1(FOCAD):c.5002A>C(p.Lys1668Gln) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. 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. K1668N) has been classified as Pathogenic.
