Copy number variations (CNVs) involving <jats:italic>PARK2<\/jats:italic> have been associated with autism spectrum disorder (ASD).

They both had dysmorphic facial features with coarse faces, deeply set eyes with long horizontal palpebral fissures, long eyelashes and thick eyebrows, fleshy lips and mild skeletal problems. We found an intrafamilial clinical heterogeneity owing to different severity of the autism symptoms between the affected sibs: the younger one had minimally verbal autism and severe intellectual disability, whereas his older brother presented high\u2010functioning autism and preserved speech. Parental analysis and real\u2010time PCR using a PRKN fragment mapping within the deletion demonstrated that the deletion was inherited from their father having subthreshold features of ASD consisting with broad autism phenotype.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The study corroborates the hypothesis that <jats:italic>PARK2<\/jats:italic> aberrations may be associated with ASD and highlights correlations between CNV affecting <jats:italic>PARK2<\/jats:italic> and ASD in a multiplex family.
