Phenotype and psychometric characterization of Phelan-McDermid syndrome patients: pioneering towards personalized medicine.

ABSTRACT:

Introduction

Phelan-McDermid syndrome (PMS) is a genetic disorder caused by the loss of the terminal region of chromosome 22 or by pathogenic or likely-pathogenic variants in SHANK3 gene. Individuals with PMS are affected by a variable degree of intellectual disability, delay or absence of speech, low muscle tone, motor delay epilepsy, and autistic features. We have performed an observational trial aimed to psychometrically characterize individuals carrying deletions or pathogenic variants in SHANK3, to eventually build a foundation for a subsequent precision psychiatry clinical trial with vafidemstat, a LSD1 inhibitor in Phase II clinical development.

Methods

We have conducted a pilot study to clinically characterize the profile of 30 subjects, all diagnosed o
