Cerebellar and Pontocerebellar Hypoplasia
Gene: ISPD
PMID: 22522421 - 11 patients with severe WWS, only two survived beyond 2 years of age. "Routine cerebral MRI
showed typical features of cobblestone lissencephaly together with hydrocephalus, cerebellar hypoplasia and a kinked brainstem".
10/11 patients either had chet mutations (missense, PTC) or homozygous PTCs/exon deletions, and diagnosed with either WSS or MEB. A single patient was homozygous for a missense. 10/11 reported specifically with "cerebellar abnormalities", no specific numbers for cerebellar hypoplasia.
PMID: 22522420 - single patient with WWS, chet for exon deletions/PTC. MRI taken at 5 months of age shows hypoplastic brainstem and cerebellar vermis.
