Added comment: Twenty individuals from seven families reported with de novo or transmitted haploinsufficient variants in SF3B2. Affected individuals had mandibular hypoplasia, microtia, facial and preauricular tags, epibulbar dermoids, lateral oral clefts in addition to skeletal and cardiac abnormalities.

Targeted morpholino knockdown of SF3B2 in Xenopus resulted in disruption of cranial neural crest precursor formation and subsequent craniofacial cartilage defects, supporting a link between spliceosome mutations and impaired neural crest development in congenital craniofacial disease.

The families were ascertained from a cohort and the authors suggest that haploinsufficient variants in SF3B2 are the most prevalent genetic cause of CFM, explaining ~3% of sporadic and ~25% of familial cases.
