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: Benign. The variant received -14 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0315 CDS is truncated, and there are 1 pathogenic variants in the truncated region.
• BP6: Variant 2-44301128-GT-G is Benign according to our data. Variant chr2-44301128-GT-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 336199.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.242 is higher than 0.05.
