Summary

Heart and brain malformation syndrome (HBMS) is a severe autosomal recessive multiple congenital anomaly syndrome characterized by profoundly delayed psychomotor development, dysmorphic facial features, microphthalmia, cardiac malformations, mainly septal defects, and brain malformations, including Dandy-Walker malformation (summary by Shaheen et al., 2016). Homozygous mutation in the SMG9 gene can also cause neurodevelopmental disorder with intention tremor, pyramidal signs, dyspraxia, and ocular anomalies (NEDITPDO; 619995), a less severe neurodevelopmental disorder.
