Recurrent homozygous MED22:c.397_399del (p.Glu133del) inframe variant in 8 individuals from 6 families w progressive NDD, microcepahly, cerebellar atrophy, dystonia, seizures

Rare in gnomad v4.1 (9 het alleles, no homozygotes)

Functional work on patient fibroblasts: quantity of protein comparable to controls, did not mentioned assays of protein function (?mechanism proposed)
Drosophilia heterozygous model with equivalent of p.Glu133del variant: structural anomalies, less movements, all died prior to pupae stage
Zebrafish: MED22 mutants less mobile, died prior to adulthood, reduced brain size
