Genetic Variant SLC1A5:p.Ala277Ser (chr19-46778904-C-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_005628.3(SLC1A5):c.829G>T(p.Ala277Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000000712 in 1,404,290 control chromosomes in the GnomAD database, with no homozygous occurrence. 14/22 in silico tools predict 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. A277T) has been classified as Uncertain significance.

Genes affected

SLC1A5 (HGNC:10943): (solute carrier family 1 member 5) The SLC1A5 gene encodes a sodium-dependent neutral amino acid transporter that can act as a receptor for RD114/type D retrovirus (Larriba et al., 2001 [PubMed 11781704]).[supplied by OMIM, Jan 2011]
