Genetic Variant SLCO2A1:p.Arg252Gly (chr3-133951315-G-C) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_005630.3(SLCO2A1):c.754C>G(p.Arg252Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,804 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R252Q) has been classified as Uncertain significance.

Genes affected

SLCO2A1 (HGNC:10955): (solute carrier organic anion transporter family member 2A1) This gene encodes a prostaglandin transporter that is a member of the 12-membrane-spanning superfamily of transporters. The encoded protein may be involved in mediating the uptake and clearance of prostaglandins in numerous tissues. [provided by RefSeq, Dec 2011]
