Fetal anomalies v1.122 DCAF15 Chirag Patel gene: DCAF15 was added
gene: DCAF15 was added to Fetal anomalies. Sources: Other
Mode of inheritance for gene: DCAF15 was set to BIALLELIC, autosomal or pseudoautosomal
Phenotypes for gene: DCAF15 were set to Cornelia de Lange syndrome
Review for gene: DCAF15 was set to AMBER
Added comment: ESHG 2023:
3 unrelated cases with CdLS (1 x TOP with MCA, 1 x death @20mths, 1 x living child)
Features suggestive of CdLS - DD, microcephaly, CHD, dysmorphism, visual/hearing impairment.

WES identified recurrent de novo variant (p.Ser470Phe) in DCAF15 gene. This mediates ubiquitination and degradation of target proteins, and interacts with cohesin complex members (SMC1/SMC3).

Protein analysis from individuals showed increased accumulation of ubiquitination-modified proteins and SM3 (GOF mechanism). EpiSign analysis showed same DNA methylation pattern as other CdLS cases/genes. Zebrafish model showed reduced body length, reduced head size, reduced oligodendrocytes, heart defect, aberrant motor neurons, and abnormal response to visual/auditory stimuli.
