-Relevance to Autism
De novo missense variants in the CHST2 gene have been identified in ASD probands, including a de novo missense variant (p.Arg52Pro) in a proband from the Simons Simplex Collection (Iossifov et al., 2014; Yuen et al., 2017). Functional assessment of the ASD-associated p.Arg52Pro missense variant in Drosophila using a rescue-based strategy in Macrogliese et al., 2022 demonstrated that the CHST2-p.Arg52Pro mutation resulted in a reduced ability to rescue TG4 lethality in humanized flies compared with reference animals, consistent with a loss-of-function effect.
Molecular Function
This locus encodes a sulfotransferase protein. The encoded enzyme catalyzes the sulfation of a nonreducing N-acetylglucosamine residue, and may play a role in biosynthesis of 6-sulfosialyl Lewis X antigen.

Suggestive Evidence


Score Delta: Score remained at 3
criteria met
See SFARI Gene'scoring criteriaThe literature is replete with relatively small studies of candidate genes, using either common or rare variant approaches, which do not reach the criteria set out for categories 1 and 2. Genes that had two such lines of supporting evidence were placed in category 3, and those with one line of evidence were placed in category 4. Some additional lines of "accessory evidence" (indicated as "acc" in the score cards) could also boost a gene from category 4 to 3.
