dc.description.abstractPurpose : Cri-du-Chat Syndrome (CdCS) iS a rare but Clinically recongnizable Condition with an estimated incidence of 1:50,000 live births. The clinical characteristics of the syndrome include severe psychomotor and mental retardation, microcephaly, hypertelorism, hypotonia, and slow growth. Also the size of the chromosome 5p deletion ranges were known from the region 5p13 to the terminal region. In this study, we report the spectrum of 5p deletion in Korean 20 pts. with CdCs and genotype-Phenotype associations in CdCs.



Methods : In Order to delineate genotype-Phenotype Correlation, molecular Cytogenetic Studies including GT G banding and clinical characterization were performed on Korean 20 pts with CdCs including Parents. CGH array and Fluorescence in situ hybridization (FISH) analysis were used to confirm a terminal deletion karyotype and map more precisely the location of the deletion breakpoint.



Results : Molecular analysis of the spectrum of 5p deletion revealed 9 pts (45%) with a del (5) (p014), 7 pts. (35%) a del (5) (p13), 3 pts. (15%) a del (5) (p15.1) and 1 pl. (5%) a del (5) (p15.2) in 20 pts with CdCs. 4(20%)pts were identified to have additional chromosome abnormalites of deficiency and duplication involving chromosomes of 6, 8, 18, & 22. Parental study identified 3 familial case (2 paternal and 1 maternal origin) showing parents being a balanced translocation carrier. And the comparison study of the deletion break points among these 20 pts. with their phenotype has showed the varying clinical phono-types in the CdCs critical region.



Conclusion : The characterizatiorl of 5p deletion including parental study may help to delineate the genotypephenotype correlation in CdCs. Also these molecular cytogenetic analyses will be able to offer better information for accurate genetic diagnosis in CdCs and further make possible useful genetic counseling in pts. and family.
