The symptoms displayed by the infant manifest are Down syndrome. Klinefelter syndrome is least noticeable in infants. The symptoms of this syndrome appear during puberty and are noticeable by long legs, unlike the short limbs in downs syndrome. Turner’s syndrome in infants mainly displays symptoms like wide and webbed-like necks as Cri du Chat syndrome manifests almost the same symptoms as Down’ssyndrome except for the different cries in babies. Infants with Cri du Chat syndrome produce a cat-like cry (Espirito Santo et al., 2016). The probability of getting an infant with Down syndrome increases with the age of the mother. Women over the age of 40have a high probability of giving birth to infants with this condition compared to their younger counterparts.
A chromosomal abnormality mainly causes Down’ssyndrome Down’ssyndrome. People with this syndrome often have an abnormal cell division pattern due to an extra copy of genetic material in chromosome 21 (Bush et al., 2019). The process of trisomy is an occurrence where chromosome 21 fails to disjoin or normally divide within the sperm or egg. The process leaves an extra chromosome 21 in each of the cells. This error in cell division is known as nondisjunction. Analyzing this chromosomal abnormality is conducted through a karyotype. Duodenal stenosis is a condition where infants have a closure at the first part of the duodenum and is most common in those with Down syndrome. This condition causes one to lose electrolytes and fluid secreted by the stomach. Individuals diagnosed are most likely to develop hypertension in their lifetime. Pulmonary hypertension or arterial vessel tension and damage is due to immature development brought about by the syndrome (Bush et al., 2019). This syndrome causes cardiovascular malformations due to the full or partial trisomy of chromosome 21.
