-Relevance to Autism
Two de novo variants (one splice-site variant, one missense variant) in the DPP3 gene were identified in ASD probands from the Autism Sequencing Consortium in De Rubeis et al., 2014. TADA analysis of 4,504 ASD trios and 3,012 unaffected control/siblings trios from trio-based exome/genome sequencing studies identified DPP3 as an ASD candidate gene with a q-value < 0.1 (Du et al., 2019).
Molecular Function
This gene encodes a protein that is a member of the M49 family of metallopeptidases. This cytoplasmic protein binds a single zinc ion with its zinc-binding motif (HELLGH) and has post-proline dipeptidyl aminopeptidase activity, cleaving Xaa-Pro dipeptides from the N-termini of proteins.

Strong Candidate
Two de novo variants (one splice-site variant, one missense variant) in the DPP3 gene were identified in ASD probands from the Autism Sequencing Consortium in De Rubeis et al., 2014. TADA analysis of 4,504 ASD trios and 3,012 unaffected control/siblings trios from trio-based exome/genome sequencing studies identified DPP3 as an ASD candidate gene with a q-value < 0.1 (Du et al., 2019).
Score Delta: Score remained at 2
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.
