Abstract excerpt
The clinical spectrum of Phelan-McDermid syndrome (PMS) is varied, with wide-ranging degrees of intellectual disability, developmental delays, behavioral abnormalities, and medical features. Different types of genetic variation lead to PMS, and differing genotypes (e.g., size of deletion or type of variant) account for some of this variability, with strong associations between genotype and phenotype observed with...
