Cri-du-chat syndrome (CdCS) or 5p deletion syndrome is a rare chromosomal disease caused by a partial deletion on the short arm of chromosome 5. The destruction of this genetic material interferes with the expression of important genes governing brain and laryngeal development, resulting in severe neurodevelopmental and structural defects. CDCS individuals are usually characterized by a complex of cognitive defects and motor retardation, and other characteristic facial features 1. The disorder significantly influences the general development and growth as a lifelong experience wherein physical and intellectual issues require them to support and undergo therapy continually. What happens to arrive at the problem? The development of CdCS usually takes place de novo, that is, spontaneously, and it is not passed to the parents. The deletion of chromosomes occurs during what is referred to as gametogenesis or in early embryonic cell division, which sees the structural break of chromosome 5. CdCS can also be related to an unbalanced translocation that a carrier parent inherits. The deleted critical regions, particularly deleted 5p15.2 and 5p15.3, cover genes like SEMA5A and CTNND2, which play an essential role in neuronal connectivity and cortical organization. The degree of genetic losses is directly proportional to the degree of clinical manifestations, which shows the connection between genotype and phenotype in chromosomal disorders. What are the symptoms? The syndrome is characterized by a distinctive complex of physical and neurological disorders that can be observed since birth. The affected infants are known to cry cat-like, which is high-pitched and associated with undeveloped laryngeal structures in addition to microcephaly, low birth weight, low motility, and hypertelorism. There is a severe intellectual disability and significant delays in developmental milestones. As the children grow, their motor coordination could be impaired, their speech could be delayed, and they may have behavioral problems. These symptoms are of different degrees of severity based on the size of chromosomal deletion, but they all contribute to developmental and cognitive impairment of a high degree that needs to be managed throughout his or her lifetime. How is the problem treated? There is no curative treatment for Cri-du-chat syndrome nowadays. The management is mainly supportive and aims at enhancing the developmental outcomes and quality of life. Physical, occupational, and speech therapy as a part of an early intervention program can significantly increase functional abilities and communication skills. Associated complications that constitute scoliosis, cardiac or feeding problems, have to be dealt with through medical monitoring. Psychological and genetic counseling is a part of assisting the impacted families, offering future reproduction choice, and assisting them in adapting to the chronic condition of the disorder. One interesting fact about the disorder This cat-like cry, the distinctive feature of CdCS, is obtained due to the malformation and underdevelopment of the structures of the larynx and epiglottis. It is interesting to note that this cry subsides typically...
