Genes affected

SLC29A1 (HGNC:11003): (solute carrier family 29 member 1 (Augustine blood group)) This gene is a member of the equilibrative nucleoside transporter family. The gene encodes a transmembrane glycoprotein that localizes to the plasma and mitochondrial membranes and mediates the cellular uptake of nucleosides from the surrounding medium. The protein is categorized as an equilibrative (as opposed to concentrative) transporter that is sensitive to inhibition by nitrobenzylthioinosine (NBMPR). Nucleoside transporters are required for nucleotide synthesis in cells that lack de novo nucleoside synthesis pathways, and are also necessary for the uptake of cytotoxic nucleosides used for cancer and viral chemotherapies. Multiple alternatively spliced variants, encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008]

POLR1C (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0048289895).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0164 (2489/151432) while in subpopulation NFE AF= 0.0257 (1747/67868). AF 95% confidence interval is 0.0247. There are 31 homozygotes in gnomad4. There are 1191 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd at 2490 AD gene.
