Genes affected
SLC23A1 (HGNC:10974): (solute carrier family 23 member 1) The absorption of vitamin C into the body and its distribution to organs requires two sodium-dependent vitamin C transporters. This gene encodes one of the two transporters. The encoded protein is active in bulk vitamin C transport involving epithelial surfaces. Previously, this gene had an official symbol of SLC23A2. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.586G>A (p.V196I) alteration is located in exon 6 (coding exon 6) of the SLC23A1 gene. This alteration results from a G to A substitution at nucleotide position 586, causing the valine (V) at amino acid position 196 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
