SETD2 encodes an important protein for epigenetic modification of histones which plays an essential role in early development. Variants in SETD2 have been reported in neurodevelopmental disorders including autism spectrum disorder (ASD). However, most de novo SETD2 variants were reported in different large-cohort sequencing studies, mutation pattern and comprehensive genotype-phenotype correlations for SETD2 are still lacking. We have applied target sequencing to identify rare, clinical-relevant SETD2 variants and detected two novel de novo SETD2 variants, including a de novo splicing variant (NM_014159: c.4715+1G>A) and a de novo missense variant (c.3185C>T: p.P1062L) in two individuals with a diagnosis of ASD. To analyze the correlations between SETD2 mutations and corresponding phenotypes, we systematically review the reported individuals with de novo SETD2 variants, classify the pathogenicity, and analyze the detailed phenotypes. We subsequently manually curate 17 SETD2 de novo variants in 17 individuals from published literature. Individuals with de novo SETD2 variants present common phenotypes including speech and motor delay, intellectual disability, macrocephaly, ASD, overgrowth and recurrent otitis media. Our study reveals new SETD2 mutations and provided a relatively homozygous phenotype spectrum of SETD2-related neurodevelopmental disorders which will be beneficial for disease classification and diagnosis in clinical practice.
