Genes affected
SLC43A2 (HGNC:23087): (solute carrier family 43 member 2) This gene encodes a member of the L-amino acid transporter-3 or SLC43 family of transporters. The encoded protein mediates sodium-, chloride-, and pH-independent transport of L-isomers of neutral amino acids, including leucine, phenylalanine, valine and methionine. This protein may contribute to the transfer of amino acids across the placental membrane to the fetus. [provided by RefSeq, Mar 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.1001C>T (p.T334M) alteration is located in exon 9 (coding exon 8) of the SLC43A2 gene. This alteration results from a C to T substitution at nucleotide position 1001, causing the threonine (T) at amino acid position 334 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
