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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.472C>G (p.H158D) alteration is located in exon 3 (coding exon 2) of the SLC7A3 gene. This alteration results from a C to G substitution at nucleotide position 472, causing the histidine (H) at amino acid position 158 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
