ABSTRACT
A 32-year-old female patient and her sister show high levels of high density lipoprotein (HDL) cholesterol in regular health checkups, since female patient was 11 years old. The patient's serum total cholesterol was 285 mg/dL and HDL cholesterol was 113 mg/dL. Her sister's total cholesterol was 240 mg/dL and the HDL cholesterol measured to be 90 mg/dL. Lipoprotein pattern and cholesteryl ester transfer activity gene analysis were examined in these patients. We found c.1321+1G>A (IVS14+1G/A) hetero mutation in cholesteryl ester transfer protein (CETP) genes. Generally, CETP mediates transfer and exchange of triglycerides and cholesteryl ester between plasma lipoproteins. Also we investigated a key role of HDL-CE and Apo A-1 metabolism. Patients with low levels of CETP have increased serum HDL levels. We hereby report two Korean cases of CETP deficiency in a family. Brief literature review ensues with the cases.

Trisomy 9 syndrome was first reported by Retheore in 1970 and has been rarely reported. This syndrome consists of partial and complete trisomy 9. It is characterized by growth and mental retardation, craniofacial abnormalities including microcephaly, hypertelorism, prominent nose, deep-set ears and down-slanting palpebral fissures. Congenital heart diseases and congenital dislocations of knee are also common in trisomy 9 syndrome. Here, we report a very rare case of partial trisomy 9 due to maternal balanced translocation t(9;21). He showed craniofacial abnormalities, brain malformation, cardiac defect, hydronephrosis and congenital dislocations of hip and knee joints.
