Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_153811.3(SLC38A6):c.323A>C(p.Tyr108Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000000687 in 1,455,950 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. Y108C) has been classified as Uncertain significance.
