Genes affected
SLC28A3 (HGNC:16484): (solute carrier family 28 member 3) Nucleoside transporters, such as SLC28A3, regulate multiple cellular processes, including neurotransmission, vascular tone, adenosine concentration in the vicinity of cell surface receptors, and transport and metabolism of nucleoside drugs. SLC28A3 shows broad specificity for pyrimidine and purine nucleosides (Ritzel et al., 2001 [PubMed 11032837]).[supplied by OMIM, Mar 2008]
SLC28A3-AS1 (HGNC:55460): (SLC28A3 regulatory antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.1456T>C (p.C486R) alteration is located in exon 15 (coding exon 14) of the SLC28A3 gene. This alteration results from a T to C substitution at nucleotide position 1456, causing the cysteine (C) at amino acid position 486 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
