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. [provided by RefSeq, Jul 2008] 
 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: Uncertain_significance. The variant received 5 ACMG points.
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, 0.971
