Invitae RCV000417258 SCV000965292 likely pathogenic Hypercholesterolemia, autosomal dominant, 3 2018-12-12 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with asparagine at codon 129 of the PCSK9 protein (p.Asp129Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs778738291, ExAC 0.002%). This variant has been observed in individuals affected with familial hypercholesterolemia (PMID: 23680767, 19081568, 23064986, 26374825, Invitae). ClinVar contains an entry for this variant (Variation ID: 375844). Experimental studies have reported conflicting results on whether this missense change results in a reduction in LDL-receptor protein (PMID: 19081568, 23064986, 26195630). The observation of one or more missense substitutions at this codon (p.Asp129Asn and p.Asp129Gly) in affected individuals suggests that this may be a clinically significant residue (PMID: 27280970, 17765244). 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.
