Genetic Variant EFCAB14:p.Gly190Val (chr1-46696561-C-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_014774.3(EFCAB14):c.569G>T(p.Gly190Val) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,016 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. G190E) has been classified as Uncertain significance.
