In addition, this variant has been reported in a consanguineous family alon g with a second hypercholesterolemia variant (LDLRAP1 p.Gly136X). In this family , disease severity correlated with the various combinations of heterozygosity or homozygosity for the two variants (Soufi 2013). The p.Gln254Pro variant has als o been reported in ClinVar (Variation ID 251437) and was absent from large popul ation studies. In summary, although additional studies are required to fully est ablish its clinical significance, the p.Gln254Pro variant is likely pathogenic.
Department of Human Genetics,Laborarztpraxis Dres. Walther, Weindel und Kollegen RCV000237699 SCV000987041 pathogenic Familial hypercholesterolemia 1 2018-12-19 criteria provided, single submitter clinical testing The mutation at protein level leads to an amino acid exchange of glutamine to proline at position 254 (233rd amino acid of the mature protein) in the LDL receptor. This change has already been described in the literature as FH Reggio Emilia-2, as well as in patients with familial hypercholesterolaemia. We observed this variant in a patient with TC up to 360 mg/dl and LDL-C approx 300 mg/dl at the age of 55. PMID: 14974088, 11754108, 23375686
