Teratology of fallot is typically treated by open heart surgery in the first year of life. [8] The timing of surgery depends on the baby's symptoms and size. [ 8 ] The procedure involves increasing the size of the pulmonary valve and pulmonary arteries and repairing the ventricular septal defect. [ 8 ]
18p-, also known as monosomy 18p, deletion 18p syndrome, del(18p) syndrome, partial monosomy 18p, or de Grouchy syndrome 1, is a genetic condition caused by a deletion of all or part of the short arm (the p arm) of chromosome 18. It occurs in about 1 of every 50,000 births.
The symptoms may vary, depending on the exact location of the chromosomal deletion. [1] The condition is caused by a genetic deletion (loss of a segment of DNA) on the outermost band on the short arm (p) of chromosome 1. It is one of the most common deletion syndromes. The syndrome is thought to affect one in every 5,000 to 10,000 births. [2]
DiGeorge syndrome, also known as 22q11.2 deletion syndrome, is a syndrome caused by a microdeletion on the long arm of chromosome 22. [7] While the symptoms can vary, they often include congenital heart problems , specific facial features, frequent infections, developmental disability , intellectual disability and cleft palate .

The VACTERL association (also VATER association, and less accurately VACTERL syndrome) refers to a recognized group of birth defects which tend to co-occur (see below). This pattern is a recognized association, as opposed to a syndrome , because there is no known pathogenetic cause to explain the grouped incidence.
Based on symptoms and X-rays, confirmed by genetic testing [4] Differential diagnosis: Mandibuloacral dysplasia, pyknodysostosis, osteogenesis imperfecta, Hajdu-Cheney syndrome [5] Treatment: Supportive care [5] Prognosis: Normal life expectancy [3] Frequency: One per million people [1]
Axenfeld–Rieger syndrome is a rare autosomal dominant [2] disorder, which affects the development of the teeth, eyes, and abdominal region. [3]Axenfeld–Rieger syndrome is part of the so-called iridocorneal or anterior segment dysgenesis syndromes, [4] which were formerly known as anterior segment cleavage syndromes, anterior chamber segmentation syndromes or mesodermal dysgenesis.
Persistent fetal vasculature (PFV), also known as persistent fetal vasculature syndrome (PFVS), and until 1997 known primarily as persistent hyperplastic primary vitreous (PHPV), [1] is a rare congenital anomaly which occurs when blood vessels within the developing eye, known as the embryonic hyaloid vasculature network, fail to regress as they normally would in-utero after the eye is fully ...
