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.

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 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, 0.942
• PP5: Variant 2-44313931-T-A is Pathogenic according to our data. Variant chr2-44313931-T-A is described in ClinVar as Pathogenic. ClinVar VariationId is 37080.Status of the report is no_assertion_criteria_provided, 0 stars.
