- 13 patients from 8 families of Ashkenazi Jewish origin all had the same homozygous frameshift variant (c.981dup). Predicted to cause NMD. The variant co-segregated with disease in all available family members. The affected individuals displayed mild global developmental delay and mild to moderate intellectual disability. Additional prevalent phenotypes observed included hypotonia, behavioural challenges and short stature. Considered a founder variant (1 in 52 Ashkenazi Jews carry the variant). Also present in other populations but no homozygotes in gnomAD.
