This sequence change replaces cysteine, which is neutral and slightly polar, with phenylalanine, which is neutral and non-polar, at codon 420 of the SLCO2A1 protein (p.Cys420Phe). This variant is present in population databases (rs387907295, gnomAD 0.009%). This missense change has been observed in individual(s) with autosomal recessive primary hypertrophic osteoarthropathy (PMID: 22553128). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 37169). 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%. Experimental studies have shown that this missense change affects SLCO2A1 function (PMID: 22553128). For these reasons, this variant has been classified as Pathogenic. -
