PMID: 32487539 (2020) - Two affected sibs presenting in early infancy with impaired intestinal peristalsis, intestinal pneumatosis and dysmorphic features. Delayed motor and language development was reported in one sibling, however, the other sibling died at 5 months from cardiac arrest and therefore a psychomotor assessment was not performed. Exome sequencing identified a homozygous truncating variant (c.897+3_897+6delAAGT, p.L300Vfs*58) in ANO1 which segregated with disease in the family. Functional data revealed that the variant led to lack of expression of functional TMEM16A in patient cells, which in turn abolished calcium-activated Cl- currents. Also supportive mouse model.
