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.
The effects of early-life exposures to anesthesia on the brain in humans are controversial. Evidence from nonhuman primate research suggests significant developmental neurotoxicity and long-term social impairment, with a dose–response relationship where repeated exposures cause a more severe impact than single ones.

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.

Another gene implicated in human pain insensitivity is ZFHX2, which encodes zinc finger homeobox 2. A 2018 study analysed six members of a family with inherited pain insensitivity and identified a "novel point mutation in ZFHX2, encoding a putative transcription factor expressed in small diameter sensory neurons", as the cause.
Micrognathism is a condition where the jaw is undersized. It is also sometimes called mandibular hypoplasia. [2] It is common in infants, [3] [4] but is usually self-corrected during growth, due to the jaws' increasing in size.
