Genes affected
SLC36A2 (HGNC:18762): (solute carrier family 36 member 2) This gene encodes a pH-dependent proton-coupled amino acid transporter that belongs to the amino acid auxin permease 1 protein family. The encoded protein primarily transports small amino acids such as glycine, alanine and proline. Mutations in this gene are associated with iminoglycinuria and hyperglycinuria.

NM_181776.2:c.260G>T in the SLC36A2 gene has an allele frequency of 0.041 in Ashkenazi Jewish subpopulation in the gnomAD database, including 24 homozygous occurrences. Broer et al. reported this variant in a patient with iminoglycinuria . However, iminoglycinuria was only observed when homozygous SLC36A2 G87V was combined with SLC6A20 T199M (PMID: 19033659). Pathogenic computational verdict because pathogenic predictions from DANN, EIGEN, FATHMM-MKL, MutationAssessor, MutationTaster, PrimateAI and SIFT. Taken together, we interprete this variant as Benign/Likely benign variant. ACMG/AMP criteria applied: BS1; BS2; PP3. -
