Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM4 PP3 PP5_Moderate

The NM_005630.3(SLCO2A1):​c.1279_1290delGAAGTCTACCCC​(p.Glu427_Pro430del) variant causes a conservative inframe deletion change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000359 in 1,613,730 control chromosomes in the GnomAD database, including 1 homozygotes. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Likely pathogenic (★).

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]
