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.
Early reports were split on the topic of whether ring chromosome 22 constituted a consistent syndrome or simply a finding in a heterogeneous group of intellectually disabled people. [14] One early case that drew attention to the syndrome was a report of monozygotic twin sisters with a ring 22, one of the first recorded reports of a shared ...
NNZ-2591 is a synthetic analog of cyclic glycine-proline and experimental drug developed for Angelman syndrome, Phelan-McDermid syndrome, Pitt Hopkins syndrome, [1] [2] and Prader-Willi syndrome. [ 3 ]
SHANK proteins are scaffolding proteins at glutamatergic synapses crucial for synaptic development. The disruption of SHANK genes is associated with neurocognitive impairments and disorders. The disruptions, either from mutations or deletions, are associated with disorders such as Phelan-McDermid syndrome (PMS), schizophrenia, and ASD. SHANK 3 ...

Chromosome 22 is one of the 23 pairs of chromosomes in human cells.Humans normally have two copies of chromosome 22 in each cell. Chromosome 22 is the second smallest human chromosome, spanning about 51 million DNA base pairs and representing between 1.5 and 2% of the total DNA in cells.
