Genetic Variant SLC43A2:p.Met506Val (chr17-1576629-T-C) – 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_152346.3(SLC43A2):c.1516A>G(p.Met506Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000206 in 1,458,070 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. M506L) has been classified as Uncertain significance.

Genes affected

SLC43A2 (HGNC:23087): (solute carrier family 43 member 2) This gene encodes a member of the L-amino acid transporter-3 or SLC43 family of transporters. The encoded protein mediates sodium-, chloride-, and pH-independent transport of L-isomers of neutral amino acids, including leucine, phenylalanine, valine and methionine. This protein may contribute to the transfer of amino acids across the placental membrane to the fetus. [provided by RefSeq, Mar 2016]
