22q13 deletion syndrome, known as Phelan–McDermid syndrome (PMS), is a genetic disorder caused by deletions or rearrangements on the q terminal end (long arm) of chromosome 22. Any abnormal genetic variation in the q13 region that presents with significant manifestations ( phenotype ) typical of a terminal deletion may be diagnosed as 22q13 ...
22q13 deletion syndrome (Phelan–McDermid syndrome) [4] is a condition caused by the deletion of the tip of the q arm on chromosome 22. Most individuals with this disorder experience cognitive delays, low muscle tone, and sleeping, eating, and behavioural issues.
Significant overlap exists between the phenotype of ring chromosome 22 and that of Phelan-McDermid syndrome, another chromosome 22 deletion syndrome. This is ascribed to a shared deletion of the SHANK3 gene at 22q13.3.

The loss of one particular gene, TBX1, is thought to be responsible for many of the characteristic features of 22q11.2 deletion syndrome, such as heart defects, an opening in the roof of the mouth (a cleft palate), distinctive facial features, and low calcium levels. A loss of this gene does not appear to cause learning disabilities, however.
n November 1954, 29-year-old Sammy Davis Jr. was driving to Hollywood when a car crash left his eye mangled beyond repair. Doubting his potential as a one-eyed entertainer, the burgeoning performer sought a solution at the same venerable institution where other misfortunate starlets had gone to fill their vacant sockets: Mager & Gougelman, a family-owned business in New York City that has ...
