Cri du chat syndrome is characterized by cat-like cry, facial dysmorphisms, microcephaly, speech delay, intellectual disability and slow growth rate, which are present with variable frequency. The typical cri du chat syndrome, due to 5p15.2 deletion, includes severe intellectual disability, facial dysmorphisms, neonatal hypotonia and pre- and post-natal growth retardation, whereas more distal deletions in 5p15.3 lead to cat-like cry and speech delay and produce the clinical picture of the atypical cri du chat syndrome, with minimal or absent intellectual impairment. In this article we report a three-generation family with an unbalanced whole arm translocation between chromosome 5 and 15 and a microdeletion of 5.5Mb involving 5p15.33-32. By reporting the smallest terminal deletion of 5p15.3 described so far and by reviewing the literature we discuss the genotype/phenotype correlations of the distal region of the cri du chat syndrome. The previously described critical region for the speech delay may be narrowed down and microcephaly, growth retardation and dysmorphic facial features can be included in the phenotypic expression of the atypical cri du chat syndrome due to 5p15.3 deletions. © 2014 Elsevier Masson SAS.

Abstract

Cri du chat syndrome is characterized by cat-like cry, facial dysmorphisms, microcephaly, speech delay, intellectual disability and slow growth rate, which are present with variable frequency. The typical cri du chat syndrome, due to 5p15.2 deletion, includes severe intellectual disability, facial dysmorphisms, neonatal hypotonia and pre- and post-natal growth retardation, whereas more distal deletions in 5p15.3 lead to cat-like cry and speech delay and produce the clinical picture of the atypical cri du chat syndrome, with minimal or absent intellectual impairment. In this article we report a three-generation family with an unbalanced whole arm translocation between chromosome 5 and 15 and a microdeletion of 5.5Mb involving 5p15.33-32. By reporting the smallest terminal deletion of 5p15.3 described so far and by reviewing the literature we discuss the genotype/phenotype correlations of the distal region of the cri du chat syndrome. The previously described critical region for the speech delay may be narrowed down and microcephaly, growth retardation and dysmorphic facial features can be included in the phenotypic expression of the atypical cri du chat syndrome due to 5p15.3 deletions. © 2014 Elsevier Masson SAS.
