Genetic Variant SLC3A1:p.Pro615Ser (chr2-44320424-C-T) – ACMG Classification: Likely_pathogenic (7 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 7 ACMG points: 7P and 0B. PM2PP2PP3_Strong

The NM_000341.4(SLC3A1):c.1843C>T(p.Pro615Ser) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. 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. P615T) has been classified as Uncertain significance.

Genes affected

SLC3A1 (HGNC:11025): (solute carrier family 3 member 1) This gene encodes a type II membrane glycoprotein which is one of the components of the renal amino acid transporter which transports neutral and basic amino acids in the renal tubule and intestinal tract. Mutations and deletions in this gene are associated with cystinuria. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.

SLC3A1 links:

PREPL (HGNC:30228): (prolyl endopeptidase like) The protein encoded by this gene belongs to the prolyl oligopeptidase subfamily of serine peptidases. Mutations in this gene have been associated with hypotonia-cystinuria syndrome, also known as the 2p21 deletion syndrome. Several alternatively spliced transcript variants encoding either the same or different isoforms have been described for this gene.[provided by RefSeq, Jan 2010]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 25 curated pathogenic missense variants (we use a threshold of 10). The gene has 4 curated benign missense variants. Gene score misZ: -3.1434 (below the threshold of 3.09). Trascript score misZ: -3.2509 (below the threshold of 3.09). GenCC associations: The gene is linked to cystinuria type A, cystinuria.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.948
