Single-nucleotide polymorphism (SNP)-based noninvasive prenatal testing (NIPT) can currently predict a subset of submicroscopic abnormalities associated with severe clinical manifestations. We retrospectively analyzed the performance of SNP-based NIPT in 80,449 referrals for 22q11.2 deletion syndrome and 42,326 referrals for 1p36, cri-du-chat, Prader-Willi, and Angelman microdeletion syndromes over a one-year period, and compared the original screening protocol with a revision that reflexively sequenced high-risk calls at a higher depth of read...

Cri du Chat syndrome (CdC) is a chromosomal abnormality (deletion of short arm of chromosome 5) associated with intellectual disability and typical anatomical abnormalities. Research up to now focuses on the management of the disease during childhood. The longer lifespan of these patients warrants deeper investigations of how and if aging could be affected by the syndrome. We decided to focus on the association of the disease with proliferative disorders. Data on proliferative disorders in a cohort of 321 patients from Italian and German Cri du Chat databases were collected...

Cri-du-chat syndrome (CDCS) is a rare innate disease attributed to chromosome 5p deletion characterized by a cat-like cry, craniofacial malformation, and altered behavior of affected children. Metabolomic analysis and a chemometric approach allow description of the metabolic profile of CDCS as compared to normal subjects. In the present work, UHPLC/MS was employed to analyze blood samples withdrawn from CDCS carriers (n=18) and normal parental subjects (n=18), all aged 0-34 years, aiming to set up a representative CDCS profile constructed from 33 targeted amino acids and biogenic amines...

The Cri du Chat syndrome (CdC) is a rare genetic disorder caused by variable size deletions of the short arm of chromosome 5 (5p-). It is well known that home-reared patients show better performances as compared to institutionalised cases, and it was reported that continuous educational intervention can ameliorate their performances. To assess the efficacy of educational intervention and to develop new CdC oriented programs of rehabilitation, we compare the results obtained for many developmental skills in two groups of CdC patients undergoing two different rehabilitation programs...

5p deletion syndrome or Cri du Chat syndrome is a autosomal deletion syndrome, caused by the de novo deletion of chromosome 5p in the majority of the cases. Clinical features include developmental delay, microcephaly, subtle facial dysmorphism and high-pitched cry. With the advent of newer techniques such as multiplex ligation-dependent probe amplification, rapid diagnosis is possible and chromosomal microarray helps in accurate delineation of the breakpoints. In this study, we characterized probands from two Indian families who had duplication of another chromosome in addition to deletion of 5p region...

Some genes involved in complex human diseases are particularly vulnerable to genetic variations such as single nucleotide polymorphism, copy number variations, and mutations. For example, Ras mutations account for over 30 % of all human cancers. Additionally, there are some genes that can display different variations with functional impact in different diseases that are unrelated. One such gene stands out: δ-catenin/NPRAP/Neurojungin with gene designation as CTNND2 on chromosome 5p15.2. Recent advances in genome wide association as well as molecular biology approaches have uncovered striking involvement of δ-catenin gene variations linked to complex human disorders...

Cri-du-chat syndrome is a chromosomal disorder caused by a deletion of the short arm of chromosome 5. The disease severity, levels of intellectual and developmental delay, and patient prognosis have been related to the size and position of the deletion. Aiming to establish genotype-phenotype correlations, we applied array-CGH to evaluate six patients carrying cytogenetically detected deletions of the short arm of chromosome 5 who were followed at a genetics community service. The patients' cytogenetic and clinical profiles were reevaluated...

Protein-energy malnutrition (PEM) is poorly reported in cri du chat syndrome (CDCS) (OMIM #123450), a genetic disease that causes developmental delay and global growth retardation. The objective was to determine the nutritional status at different ages in children with CDCS and factors associated with PEM. A questionnaire focused on growth and nutritional care was sent to 190 families. Among 36 analyzable questionnaires, growth and nutritional indices compatible with PEM occurred in 47% of patients: 19% before 6 months of age, 24% between 6-12 months and 34% after 12 months...

Deletion of the short arm of chromosome 5 (5p-) is associated with phenotypic features including a cat-like cry in infancy, dysmorphic facial features, microcephaly, and intellectual disability, and when encompassing a minimal critical region, may be defined as Cri-du-Chat syndrome (CdCS). Most 5p deletions are de novo in origin, and familial cases are often associated with translocation and inversion. Herein, we report three multigenerational families carrying 5p terminal deletions of different size transmitted in an autosomal dominant manner causing variable clinical findings...

Cri-du-chat syndrome (CdCs) is caused by deletion in the short arm of chromosome 5, occurring in 1:15,000 to 1:50,000 live births. Recent genotype-phenotype correlation studies show the importance of 5p15.2 for facial dysmorphism and intellectual disability, and 5p15.3 for cat-like cry. Numerous reports have shown the relative rarity of epilepsy in this syndrome. We identified two cases with epilepsy in CdCs, and described their electroclinical and cytogenetic features. The first case was a 25-year-old female who had axial tonic seizures with flexion of the neck and shoulders...

Cri du chat syndrome is an autosomal disorder. Because it affects few people in the population it is considered a rare disease, yet it is one of the most common autosomal chromosomal syndromes in humans. It entails pathognomonic alterations that affect the craniofacial and oral anatomy of patients. The aim of this study is to review these craniofacial and oral abnormalities in patients with Cri du chat syndrome. The PubMed Medline database was searched using two different strategies. First, we used "Dentistry" and "Cri du chat" as keywords; second, we used "Cri du chat" and "craniofacial...

We designed a targeted-array called GOLD (Gain or Loss Detection) Chip consisting of 900 FISH-mapped non-overlapping BAC clones spanning the whole genome to enhance the coverage of 66 unique human genomic regions involved in well known microdeletion/microduplication syndromes. The array has a 10 Mb backbone to guarantee the detection of the aneuploidies, and has an implemented resolution for telomeres, and for regions involved in common genomic diseases. In order to evaluate clinical diagnostic applicability of GOLDChip, analytical validity was carried-out via retrospective analysis of DNA isolated from a series of cytogenetically normal amniocytes and cytogenetically abnormal DNA obtained from cultured amniocytes, peripheral blood and/or cell lines...
