ASDRelevance to Autism
A de novo missense variant that was predicted to be damaging was identifed in the SUPT16H gene in an ASD proband from the Simons Simplex Collection in Iossifov et al., 2014. Bina et al., 2020 identified five individuals with de novo variants affecting the SUPT16H gene, all of whom presenting with gross motor delay, delayed or absent speech, and cognitive delay/intellectual disability; two of the five individuals from this study also presented with autistic features. Microdeletions and microduplications involving the CHD8 and SUPT16H genes have also been observed in patients presenting with a spectrum of neurodevelopmental phenotypes, including ASD/autistic features (Drabova et al., 2015; Smyk et al., 2016; Yasin et al., 2019; Smol et al., 2020).
Molecular Function
The SUPT16H gene encodes for a component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure. It facilitates the passage of RNA polymerase II and transcription by promoting the dissociation of one histone H2A-H2B dimer from the nucleosome, then subsequently promotes the reestablishment of the nucleosome following the passage of RNA polymerase II.

SFARI Gene score
Strong Candidate, Syndromic
Score Delta: Score remained at 2S
criteria met
See SFARI Gene'scoring criteriaWe considered a rigorous statistical comparison between cases and controls, yielding genome-wide statistical significance, with independent replication, to be the strongest possible evidence for a gene. These criteria were relaxed slightly for category 2.
The syndromic category includes mutations that are associated with a substantial degree of increased risk and consistently linked to additional characteristics not required for an ASD diagnosis. If there is independent evidence implicating a gene in idiopathic ASD, it will be listed as "#S" (e.g., 2S, 3S, etc.). If there is no such independent evidence, the gene will be listed simply as "S."
