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]
Individuals with ring 18 have one of their two copies of chromosome 18 that has formed the shape of a ring. The ring is formed when the caps on both the long arm (q) and the short arm (p) of one copy of chromosome 18 are lost and the new ends re-join to form the ring. Because the ring involves deletions of both the long arm (18q-) and the short ...
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]
[8] [9] The 1q21.1 area contains 20–40 genes. There are two main ways that the copy number variations of 1q21.1 might appear: Type I, which spans roughly 1.8 Mb and includes only the distal end area of 1q21.1, and type 2, which extends proximally to include the thrombocytopenia absent radius syndrome region, span around 2.7 Mb.

Tethered cord syndrome ( TCS) refers to a group of neurological disorders that relate to malformations of the spinal cord. [ 1] Various forms include tight filum terminale, lipomeningomyelocele, split cord malformations ( diastematomyelia ), occult, dermal sinus tracts, and dermoids . All forms involve the pulling of the spinal cord at the base ...
Sadie was recently diagnosed with postural orthostatic tachycardia syndrome (POTS), an incurable condition that brings about a number of symptoms including dizziness, fatigue and a rapid heart ...
Medical genetics. 2p15-16.1 microdeletion is an extremely rare genetic disorder caused by a small deletion in the short arm of human chromosome 2. First described in two patients in 2007, [1] by 2013 only 21 [citation needed] people have been reported as having the disorder in the medical literature. [2] [3] [4] [5]
Using the CT markers of visceral fat, subcutaneous fat, muscle mass, liver density, and aortic calcium, researchers were able to determine a person’s type 2 diabetes risk. Scientists found that ...
