Variant chr11-66369081-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001532.3(SLC29A2):c.394G>T(p.Ala132Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A132V) has been classified as Uncertain significance.

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]

Feb 17, 2024

The c.394G>T (p.A132S) alteration is located in exon 4 (coding exon 4) of the SLC29A2 gene. This alteration results from a G to T substitution at nucleotide position 394, causing the alanine (A) at amino acid position 132 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
