dbSNP rs914104433: MFSD3:p.Leu11Val (chr8-144509364-C-G) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_138431.3(MFSD3):c.31C>G(p.Leu11Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000114 in 1,492,442 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. L11F) has been classified as Uncertain significance.
