Added comment: - 11 probands all de novo except for 1 mother-daughter pair.
- a mix of null and missense variants
- 2/11 with microcephaly, 10/11 motor delay, 7/11 language delay (excluding 2 with regression), all with varying degrees of ID, 3/11 seizures, 7/11 movement disorder, 4/11 cerebellar ataxia, 6/11 MRI anomalies

additional variants were noted in 2 patients: 1x cHet for variants in MED12L and 1x de novo TNK2 variant

patch clamp functional studies were also done
