Chen et al., 2025 integrated cortex cell-specific cis-regulatory element annotations, a deep learning-based variant prediction model, and massively parallel reporter assays to systematically evaluate the functional impact of 227,878 non-coding de novo mutations (ncDNMs) in ASD probands from Simons Simplex Collection (SSC) and Autism Speaks MSSNG resource (MSSNG) cohorts and identified a ncDNM that down-regulated expression of the ZNF644 gene in a MSSNG proband. A de novo loss-of-function variant and a de novo missense variant have also been identified in the ZNF644 gene in ASD probands (Iossifov et al., 2014; Tan et al., 2024).
Molecular Function
The protein encoded by this gene is a zinc finger transcription factor that may play a role in eye development. Defects in this gene have been associated with high myopia (MYP21; OMIM 614167).

SFARI Gene score
Suggestive Evidence

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.
