[…] rare disease Polymicrogyria Disease definition Polymicrogyria (PMG) is a heterogenous group of cerebral cortical malformations characterized by excessive cortical folding and abnormal cortical layering that, depending on its topographic distribution, presents [orpha.net]

In more severe forms, focal, motor, sensory, visual, or cognitive problems may be present, depending on the brain region affected. [blueprintgenetics.com]

PtdIns3,5P2 is the rarest amongst the seven different PtdIns’s and is only present on the outside of endosomes. It is generated by a single molecule named PIKfyve, the Phosphoinositide kinase with a FYVE domain. [epilepsygenetics.net]

Olfactory sulci and bulbs were present in 2/3 foetuses and optic nerves were normal in all cases. [link.springer.com]

He is currently involved in multiple clinical trials of novel genetic interventions for the treatment of spinal muscular atrophy and Duchenne muscular dystrophy. [books.google.com]

Treatment and management of PMG depend on the needs of the individual. Commonly used, but not limited too, are physical therapy for gross motor impairment, orthotic devices and surgery for those with spastic motor impairment. [pmgawareness.org]

There is no specific treatment to get rid of this condition, but there are medications that can control the symptoms such as seizures, delayed development or weakened muscles as some of the noted effects. [en.wikipedia.org]

Diffuse bilateral polymicrogyria (DBP) is related to poor epilepsy prognosis, but most patients with DBP are not good candidates for resective epilepsy surgery and effectiveness of corpus callosotomy (CC), a palliative surgery, for patients without resective [ncbi.nlm.nih.gov]

Prognosis is developmental arrest at P3-5 mos. Fatal by age 2 on average for MDS, by age 10 for ILS, usually due to pneumonia. [www2.gsu.edu]

Though it is difficult to make a predictable prognosis for children with the diagnosis of PMG, there are some generalized clinical findings according to the areas of the brain that are affected. [ipfs.io]

[…] usually present not present (MSGP is usually isolated) Prognosis [ edit ] Microlissencephaly usually leads to an early fatal outcome during the neonatal period. [28] Epidemiology [ edit ] Microlissencephaly is listed in Orphanet database as a rare disease [en.wikipedia.org]

However gross analysis shows an infected patient can have as little as one to all six of these layers missing. [4] Etiology The etiology of polymicrogyria is unclear. [ipfs.io]

Polymicrogyria can result from both genetic and environmental etiologies. It can occur as an isolated event, or as a symptom or part of other brain abnormalities. [pmgawareness.org]

These clinical features might have characterized a subpopulation with a specific subtype of polymicrogyria or a specific etiology, which is certainly not representative of the larger population of individuals with polymicrogyria, in which varied etiologic [ajnr.org]

These observations suggest that the etiology for the neurological features must also be due to genes located proximal to SHANK3. [symbiosisonlinepublishing.com]

Missense mutations in the absence of nonsense mutations, frameshifts, or genomic deletions support altered protein function, rather than haploinsufficiency, as the primary genetic etiology of these tubulin-related disorders[ 28 ]. [bmcresnotes.biomedcentral.com]

Pathophysiology [ edit ] The genetic basis and pathophysiology of microlissencephaly are still not completely understood. [19] Most cases of microlissencephaly are described in consanguineous families suggesting an autosomal recessive inheritance. [7] [en.wikipedia.org]

Until recently, the different possible pathophysiological mechanisms underlying microlissencephaly remained poorly understood. [link.springer.com]
