The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. This variant is present in population databases (rs542645236, ExAC 0.001%). This variant has been observed in individuals with PAH-related disease (PMID: 26600521, 30050108, 25456745, 29390883, 21307867). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 225134). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. For these reasons, this variant has been classified as Pathogenic.
