- Flushing
High and broad forehead, sparse fronto-temporal hair, malar flushing, down-slanted palpebral fissures and a pointed chin are the most common facial traits. Macrocephaly is present as head circumference above the 97th percentile. [bredagenetics.com]
Neurologic
- Seizure
Classic signs and symptoms include polymicrogyria, megalencephaly, seizures, polydactyly, and hydrocephalus. [rarediseases.info.nih.gov]
With typical PMG, you have a higher chance of intractable seizures, with MPPH there is a higher chance of having seizures controlled by medication. [lovingluke1.blogspot.com]
The child was severely delayed with a stable seizure disorder controlled with dual antiepileptic therapy. This case meets the classic criteria for MPPH syndrome, adding to the limited experience with this disease. [casereports.bmj.com]
At 7 months, the patient developed seizures, which were controlled by medication. An electroencephalogram indicated seizure activity in the right occipital region spreading to the temporal lobe. [ajnr.org]
- Delayed Milestone
Subsequently, feeding difficulties with poor growth become more evident as the delayed milestones. Hypertonia, joint stiffness, and seizures develop rapidly, and most of the patients die in the first decade of life. [journals.lww.com]

Prognosis
[ edit ] The prognosis of megalencephaly depends heavily on the underlying cause and associated neurological disorders. [18] Because the majority of megalencephaly cases are linked with autism, the prognosis is equivalent to the corresponding condition [en.wikipedia.org]

Etiology
(Etiology) Megalencephaly-Polymicrogyria-Polydactyly-Hydrocephalus Syndrome may be caused by mutation(s) in PIK3R2, AKT3 or CCND2 gene Each gene codes for proteins involved in an important cellular chemical signaling pathway, known as the PI3K-AKT-mTOR [dovemed.com]
Older age at the time of the procedure (eg, greater than one year of age) was by far the strongest predictor of success, and noninfectious etiologies (eg, myelomeningocele, intraventricular hemorrhage, aqueductal stenosis, or tectal tumor) and lack of [es.slideshare.net]

Megalencephaly is classically defined into 3 groups, according to the etiology: idiopathic or benign, metabolic, and anatomic (Fig. 1). [journals.lww.com]
Conclusions A combination of genetic and biochemical methods was able to identify the involvement of the mTOR pathway in approximately 70% of patients with megalencephaly of an unknown etiology. [bmcmedgenet.biomedcentral.com]

Pathophysiology
Hydrocephalus occurs in 90 % of children with Dandy-Walker malformation/variant The pathophysiology of the hydrocephalus is now felt to be multifactorial. [es.slideshare.net]
Pathophysiology [ edit ] One impact of megalencephaly is the complete lack of motor development. [en.wikipedia.org]
