| Remarks |
Clinically affected; pregnancy normal, but reduced fetal movements compared to older sibling; birth at full term 8lbs 8oz; feeding problems at birth, with slow weight gain until able to pick up food and self feed at 3 yrs; delay in milestones: smiled at 10m; stood at 18m but left-side neglect; walked at 34m; dystonia from 2yrs (improved with dopamine from 16 years); speech: occasional words from 3 yrs, no fluency until improvement when dopamine given for the dystonia - this led to phrases and ‘almost sentences’; no surgery; seizures: some febrile seizures from 18m: 10 in total bad spell at 4yrs, last fit at 6 yrs; dystonia; axial and limb myoclonia; orofacial dyskinesia; distal hand tremor; early infantile hypotonia, MRI scans have shown delayed myelination with deficiency of the anterior corpus callosum, cerebellar hypoplasia and frontal underdevelopment; hyperkinesia; stereotypies and tics; de novo mutation detected in FOXG1 gene: c.695A>G (p.Asn232Ser); sleep problems managed by Clonidine; speech and movement improved with Levodopa; medications include Sinemet and Rasagiline; uses communication aid; severe verbal apraxia; moderate to severe learning disability; EEG showed no abnormalities; family history: mother had an aneurysmal subarachnoid hemorrhage, paternal grandfather had a subarachnoid hemorrhage; Same subject as GM27616 (fibro) and GM27629 (iPSC). Unaffected brother is GM27374, unaffected father is GM27376. |
