I don't know

cohort of individuals with delayed motor and speech development, ASD

8x de novo – 6x missense + 2x PTC
1x pat splice (father unaffected)
2x unknown_inh PTCs

Of the missense variants, G370E has 8 hets in gnomad v4

This gene is not constraint for LoF with 4 hets with an NMD variant in gnomad v4
3 of the missense are said to lie within a region of missense constraint, however this isn't the case in v4
