The 18p tetrasomy is a structural chromosomal abnormality with the presence of an extra isochromosome 18p, caused by a nondisjunction failure during maternal meiosis II. This additional i(18p) occurs in 1 of 180,000 live-born children worldwide, affecting males and females equally. It is characterized by craniofacial dysmorphisms; ears, nose and throat (ENT) abnormalities; musculoskeletal alterations; and global development delay. We aim to present the clinical and cytogenetic findings of a 3-year-10-month-old Latin American male with i(18p), to support the gene dosage effects, comparing his features with the ones reported in literature. This patient was product of the second pregnancy of a 39-year-old woman and the first son of a 49-year-old man. His main... |
