Disruptive de novo mutations of DYRK1A lead to a syndromic form of autism and ID.

ABSTRACT: Dual-specificity tyrosine-(Y)-phosphorylation-regulated kinase 1 A (DYRK1A) maps to the Down syndrome critical region; copy number increase of this gene is thought to have a major role in the neurocognitive deficits associated with Trisomy 21. Truncation of DYRK1A in patients with developmental delay (DD) and autism spectrum disorder (ASD) suggests a different pathology associated with loss-of-function mutations. To understand the phenotypic spectrum associated with DYRK1A mutations, we resequenced the gene in 7162 ASD/DD patients (2446 previously reported) and 2169 unaffected siblings and performed a detailed phenotypic assessment on nine patients. Comparison of our data and published cases with 8696 controls identified a significant enrichment of DYRK1A truncating mutations (P=0.00851) a
