Fetal anomalies v2.54 NUAK1 chirag patel changed review comment from: 7 individuals from 5 unrelated consanguineous families with craniofacial dysmorphism (hypertelorism, DSPF, dental anomalies), neurodevelopmental issues, and omphalocele (2 families with LOF variants). WES identified 5 different homozygous variants (3 missense, 1 nonsense, 1 splice) which segregated with disease.

NUAK1 has a kinase function and all variants were located in the kinase domain. Patient fibroblast assays showed reduced transcript and loss of NUAK1 protein for LOF variants. The missense variants had increased transcript and protein levels but had reduced kinase activity. Mouse models show abdominal wall defects. Xenopus models showed craniofacial defects and ventral body wall defects.
