| Remarks |
Clinically affected; very high serum LDL (820 mg/L), triglycerides: 85; normal triglycerides; cutaneous and tendinous xanthomas; corneal arcus; no response to diet and bile chelating resins; fibroblast assays show minimal binding, internalization and degradation and oleate incorporation into cholesterol ester; 120I-LDL binding assay showed this line to have <5% normal activity (LDL receptor negative); Family history: mother’s side of the family reported to be strongly positive for early onset atherosclerosis and hypercholesterolemia; affected mother(GM03065)-serum cholesterol level 870 mg/L, triglycerides: 51, no xanthomas, no clinical evidence of atherosceloris; affected father(GM03064)-serum cholesterol level 299 mg/L, triglycerides: 150, no xanthomas, no clinical evidence of atherosclerosis. |
