Genes affected
SLC7A3 (HGNC:11061): (solute carrier family 7 member 3) This gene encodes a member of the solute carrier family 7. The encoded protein is a sodium-independent cationic amino acid transporter. Alternate splicing results in multiple transcripts that encoded the same protein.[provided by RefSeq, May 2010]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.1703C>T (p.A568V) alteration is located in exon 11 (coding exon 10) of the SLC7A3 gene. This alteration results from a C to T substitution at nucleotide position 1703, causing the alanine (A) at amino acid position 568 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
