Cri du chat syndrome is an inherited disease affecting multiple organ systems. Most characteristic is the anatomical abnormality of the larynx resulting in a cat-like cry. Issues important in developing an anaesthetic plan include: anatomical abnormalities of the airway, congenital heart disease, hypotonia, mental retardation, and temperature maintenance. We report the case of a 33-month-old patient with cri du chat syndrome undergoing patent ductus arteriosus (PDA) ligation and discuss the anaesthetic issues.

We report a newborn male with multiple congenital anomalies including growth retardation, hypotonia, dysmorphic facies, widely-spaced nipples, micropenis, cryptorchidism, optic nerve hypoplasia, heart disease, and a striking, high-pitched cry. Chromosome analysis revealed de novo partial trisomy 11q due to a der(5)t(5;11)(p15.3;q22). Fluorescence in situ hybridization (FISH) showed loss of the 5p telomere signal on the der(5) chromosome, indicating the infant has partial monosomy 5p in addition to partial trisomy 11q. Among cases involving trisomy 11q, an unusual cry has only been documented in the presence of a der(5)t(5p;11q). This apparent dependence of the abnormal cry on monosomy 5p suggested the same genetic mechanism that occurs in Cri du chat syndrome (CDCS) may be responsible for the atypical cry in der(5)t(5p;11q) individuals. Neither a commercial CDCS probe (LSI D5S23, D5S721) nor a series of BAC clones encompassing distal regions implicated in the CDCS-associated cat-cry were deleted in our patient. These results suggest a second cry-modifying locus maps telomeric to BAC RP11-94J21 in band 5p15.33. This locus may not only cause the abnormal cry in individuals with a der(5)t(5p;11q) but could also contribute to the phenotypic variability and discordant mapping studies observed for CDCS.

We describe a patient who had multiple malformations including ventriculomegaly, colpocephaly, corpus callosum, cerebellum and vermix hypoplasia, optic nerve hypoplasia, corneal opacity and congenital heart disease in whom a trisomy 1q32-qter and monosomy 5p derived from a t(1;5)mat was diagnosed by karyotype and FISH analysis. This trisomy/monosomy association has not been previously reported. The familial analysis of the translocation was carried out in four generations and its implications on the phenotype of the patient and genetic counseling are discussed.

OBJECTIVE To analyze the clinical features and genetic mutations in a neonate with atypical Cri-du-chat syndrome, whom only featured with weak cry but had no dysmorphic facial features and congenital heart disease. METHODS G-banding karyotyping was performed on the child and her parents. The result was validated by fluorescence in situ hybridization (FISH). Chromosome microarray (CMA) was used to further delineate the mutation. RESULTS G-banding analysis suggested that the child had a karyotype of 46,XX,del(5)(p14p15), while both of his parents had a normal karyotype. FISH confirmed the absence of D5S23 and D5S721 at 5p15.2. A 25.7 Mb deletion was detected in the 5p15.33p14.1 region by CMA. CONCLUSION The phenotype of Cri-du-chat syndrome can vary significantly among patients, particularly in neonates, and can be easily mis-diagnosed. Combined cytogenetic and molecular analysis can identify the missing fragments with greater precision.
