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]

Pathogenic:3

Likely pathogenic, criteria provided, single submitter	clinical testing	3billion	Mar 22, 2022	Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through protein truncation. The predicted truncated protein may be shortened by less than 10% . The variant has been reported at least twice as pathogenic/likely pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000225477, PMID:24153155). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency:0.0000364). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -

ClinVar contains an entry for this variant (Variation ID: 225477). For these reasons, this variant has been classified as Pathogenic. This premature translational stop signal has been observed in individual(s) with hypertrophic osteoarthropathy (PMID: 24153155, 24929850). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs776813259, gnomAD 0.03%). This sequence change creates a premature translational stop signal (p.Arg603*) in the SLCO2A1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 41 amino acid(s) of the SLCO2A1 protein. -
