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 GeneticsAug 17, 2022The c.1555G>A (p.V519M) alteration is located in exon 14 (coding exon 13) of the SLC43A2 gene. This alteration results from a G to A substitution at nucleotide position 1555, causing the valine (V) at amino acid position 519 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
