Genes affected

SLC29A2 (HGNC:11004): (solute carrier family 29 member 2) The uptake of nucleosides by transporters, such as SLC29A2, is essential for nucleotide synthesis by salvage pathways in cells that lack de novo biosynthetic pathways. Nucleoside transport also plays a key role in the regulation of many physiologic processes through its effect on adenosine concentration at the cell surface (Griffiths et al., 1997 [PubMed 9396714]).[supplied by OMIM, Nov 2008]

Ambry Genetics

Feb 23, 2023

The c.1076G>A (p.R359Q) alteration is located in exon 11 (coding exon 11) of the SLC29A2 gene. This alteration results from a G to A substitution at nucleotide position 1076, causing the arginine (R) at amino acid position 359 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
