Specialty. Medical genetics. Distal 18q- is a genetic condition caused by a deletion of genetic material within one of the two copies of chromosome 18. [1] The deletion involves the distal section of 18q and typically extends to the tip of the long arm of chromosome 18. [2]
1 per 5,000 births [3] Trisomy 18, also known as Edwards syndrome, is a genetic disorder caused by the presence of a third copy of all or part of chromosome 18. [3] Many parts of the body are affected. [3] Babies are often born small and have heart defects. [3] Other features include a small head, small jaw, clenched fists with overlapping ...
Beckwith–Wiedemann syndrome ( / ˈbɛkˌwɪθ ˈviːdə.mən /; abbreviated BWS) is an overgrowth disorder usually present at birth, characterized by an increased risk of childhood cancer and certain congenital features. A minority (<15%) of cases of BWS are familial, meaning that a close relative may also have BWS, and parents of an affected ...

18p-. 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. [ 1 ]
Proximal 18q-is a rare genetic condition caused by a deletion of genetic material within one of the two copies of chromosome 18. This deletion involves the proximal (near the centromere ) section of the long arm of chromosome 18 somewhere between 18q11.2 (18.9 Mb) to 18q21.1 (43.8 Mb). [1]
Most babies with the rare condition live only a few days.
Rates of 17 cancers have been rising among each generation since the baby boomers, with more young people being diagnosed below age 50 than in the past, new research suggests.
