Phenotypic Variability in Phelan–McDermid Syndrome and Its Putative Link to Environmental Factors
0 Comment
Phelan-McDermid Syndrome phenotypic variability and its link to environmental factors. Phelan-McDermid Syndrome (PMS) is categorized by different genetic abnormalities in the SHANK3 gene, chromosomal rearrangements and/or deletion at 22q13. The size of deletion may vary from 100 Kb to over 9 Mb and large deletions may involve many additional genes.... Read More

Phelan-McDermid syndrome and new treatment medications
Phelan-McDermid syndrome new treatments may improve some patients’ symptoms – more research necessary. Phelan-McDermid syndrome (PMS) is a disorder caused by deletions of the distal segment of 22q (22q13.3). The main factor in this condition is haploinsufficiency of the SHANK3 gene located at this segment. Mutations of this gene produce... Read More

Phelan-McDermid syndrome: genotype-phenotype correlation and identification of an atypical case
Phelan-McDermid Syndrome (PMS), also known as 22q13 Deletion Syndrome, is a rare genetic disorder caused by deletions in the 22q13.3 region involving the SHANK3 gene, Sometimes mutations in the SHANK3 gene may produce the same condition. Clinical features in patients broadly vary and include global developmental delay, intellectual disability... Read More

Phelan-McDermid Syndrome Patient Powered Research Network
This article discusses Phelan-McDermid Syndrome and the Patient Powered Research Network. Phelan-McDermid Syndrome (PMS) is a rare neurodevelopmental disorder, with only about 1,400 cases reported. It is caused either by a 22q13 deletion – a region within the long arm of chromosome 22 – or a mutation within the SHANK3... Read More
