Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). 18 individuals from 15 unrelated families were identified with different heterozygous variants in the RFX3 gene (14 de novo, 1 inherited). Presenting phenotypes include ID/GDD (14/18), ASD (13/18) and ADHD (10/18).

There are sufficient unrelated cases with a relevant phenotype associated with variants in this gene to rate as Green at the next GMS panel update.

Zornitza Stark (Australian Genomics)

Green List (high evidence)

Report of 38 individuals (from 33 unrelated families) with de novo or inherited loss of function variants in RFX3 (15 families), RFX4 (4 families), and RFX7 (14 families), identified through WES. Individuals share neurobehavioural features including ASD, intellectual disability, and/or ADHD; other frequent features include hypersensitivity to sensory stimuli and sleep problems. RFX3, RFX4, and RFX7 are strongly expressed in developing and adult human brain, and X-box binding motifs as well as RFX ChIP-seq peaks are enriched in the cis-regulatory regions of known ASD risk genes. These genes are potentially critical transcriptional regulators of neurobiological pathways associated with neurodevelopmental disease pathogenesis.
