Essays: At Least 300 Words Per Prompt: Kate Is Born With ✓ Solved

Essays: (at least 300 words per prompt) 1. Kate is born with features that do not look quite normal. Her eyes are wide-set and slightly slanted. Her nose is short and flat, and she keeps her mouth slightly open. There is a straight crease across her palm, and her fifth digit is unusually short. The doctor tells her parents she has an inherited disorder. If you were the doctor what would you diagnosis Kate with? Discuss the etiology of Kate’s disorder? What is the biggest risk factor for this disorder? How can or will this disorder affect Kate? What test could have been completed to diagnosis this disorder before Kate’s birth?

Based on the described features—wide-set, slightly slanted eyes, a short flat nose, a persistently open mouth, a straight palm crease, and a shortened fifth digit—there is a strong suspicion that Kate may have Cri du Chat syndrome, also known as 5p- syndrome. This is a genetic disorder resulting from a deletion of the short arm of chromosome 5, which leads to the characteristic physical features and developmental delays observed in affected individuals.

The etiology of Cri du Chat syndrome is rooted in chromosomal aberrations, typically a de novo deletion during gametogenesis, meaning it usually occurs spontaneously without a family history. This deletion involves a variable part of the p arm of chromosome 5, leading to the loss of critical genes that influence physical and neurological development. The size of the deletion can vary among affected individuals, correlating with the severity of symptoms. The biggest risk factor for this disorder is advanced maternal age, as the likelihood of chromosomal nondisjunction increases with maternal age, leading to errors in chromosome segregation during meiosis.

This disorder profoundly affects an individual's growth, cognitive development, and physical health. Children with Cri du Chat often experience intellectual disabilities, delayed speech and motor skills, distinctive facial features, and characteristic features such as a low birth weight and hypotonia. The high-pitched cat-like cry, which gives the syndrome its name, is often a hallmark sign observed in infancy, due to laryngeal abnormalities. Over time, these children may face challenges with learning, speech, and social interactions, necessitating multidisciplinary intervention and comprehensive care.

Early diagnosis of Cri du Chat syndrome is possible through genetic testing. A karyotype analysis can detect deletions on chromosome 5, confirming the diagnosis postnatally. However, to diagnose the disorder prenatally, multiple tests can be employed, such as chorionic villus sampling (CVS) or amniocentesis, which analyze fetal chromosomes for deletions. Fluorescence in situ hybridization (FISH) and array comparative genomic hybridization (array CGH) are more sensitive techniques that can identify submicroscopic deletions with higher precision. These testing options enable early detection and prenatal counseling, helping prospective parents understand the prognosis and plan for necessary medical and developmental support.
