Megjegyzések:	Smith-Lemli-Opitz (SLO) syndrome is an autosomal recessivedisorder characterized by multiple congenital abnormalitiesand mental retardation. The condition is caused by the deficiencyof 7-dehydrocholesterol reductase (DHCR7) whichcatalyzes the final step in cholesterol biosynthesis. Biochemicaldiagnosis is based on increased concentration of 7-dehydrocholesterol(7-DHC) in the patient serum. Both life expectancyand quality of life are severely affected by the disease.The estimated prevalence of SLO syndrome ranges between1: 20,000 and 1: 40,000 among Caucasians. Although the mutationalspectrum of the disease is wide, approximately 10mutations are responsible for more than 80% of the cases.These mutations show a large interethnic variability. Thereare no mutation distribution data from Hungary to date.Thirteen patients were diagnosed with SLO syndrome in ourlaboratory. As first-line tests, serum 7-DHC and total cholesterolwere measured and, in positive cases, molecular geneticanalysis of the DHCR7 gene was performed. Completegenetic background of the disease could be identified in 12cases. In 1 case only 1 mutation was detected in a heterozygoteform. One patient was homozygous for the commonsplice site mutation c.964?1G 1 C, while all other patientswere compound heterozygotes. One novel missense mutation,c.374A 1 G (p.Tyr125Cys) was identified.
