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.

Biotechnology Lab, University of Central Punjab

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: research

A molecular and computational study performed on the Pakistani population reported this synonymous variant (G38=) in the SLC3A1 gene, as a benign variant, by using the technique of Next-generation sequencing. This variant might be the reason for causing the disease or increasing the severity of the already inherited Cystinuria. The variant was confirmed by ARMS-PCR at the population level (Zafar & Awais, 2023). -

Illumina Laboratory Services, Illumina

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
