Relevance to Autism
Truncating variants on the paternal allele of the MAGEL2 gene were identified in four individuals presenting with autism spectrum disorder (ASD), intellectual disability and a varying degree of clinical and behavioral features of Prader-Willi syndrome (PWS) (Schaaf et al., 2013).
Molecular Function
The protein encoded by this paternally-imprinted gene may enhance ubiquitin ligase activity of RING-type zinc finger-containing E3 ubiquitin-protein ligases and has been proposed to act through recruitment and/or stabilization of the Ubl-conjugating enzyme (E2) at the E3:substrate complex. This gene may play a role in Prader-Willi syndrome (PWS, OMIM 176270), a contiguous gene syndrome characterized by muscular hypotonia, mental retardation, short stature, obesity, hypogonadotropic hypogonadism, and small hands and feet that results from inactivity of the paternal copies of a number of genes on 15q11, through deletion or disruption of these genes or maternal uniparental disomy 15.
