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]

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 104 of the SLCO2A1 protein (p.Gly104Arg). This variant is present in population databases (rs387907297, gnomAD 0.05%). This missense change has been observed in individual(s) with primary hypertrophic osteoarthropathy (PMID: 30931527). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 1350810). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt SLCO2A1 protein function with a positive predictive value of 80%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
