Recently, the molecular genetic and cellular bases of an increasing number of neurocutaneous disorders have been unravelled, shedding light on the interplays between common intra- and extra-neuronal signalling pathways encompassing receptor-protein and protein-to-protein cascades (eg, RAS, MAPK, mTOR, PI3K/AKT and GNAQ pathways), which are often responsible of the mosaic distribution of cutaneous and extra-cutaneous features.
Sjögren-Larsson syndrome (SLS) is an autosomal recessive neurocutaneous disorder caused by mutation in the ALDH3A2 gene that codes for human fatty aldehyde dehydrogenase (FALDH).
Sjögren-Larsson syndrome (SLS, MIM 270200) is a rare autosomal recessive neurocutaneous disorder due to a deficiency of the fatty aldehyde dehydrogenase and defined by a characteristic triad of symptoms including congenital ichthyosis, spastic di- or quadriplegia and mental retardation.
Vascular hyperpermeability as a hallmark of phacomatoses: is the etiology angiogenesis comparable with mechanisms seen in inflammatory pathways? Part I: historical observations and clinical perspectives on the etiology of increased CSF protein levels, CSF clotting, and communicating hydrocephalus: a comprehensive review.
Sturge-Weber syndrome (SWS) is a vascular neurocutaneous disorder that results from a somatic mosaic mutation in GNAQ, which is also responsible for isolated port-wine birthmarks.

This case expands our knowledge of the genetic basis for phacomatosis, in which mutations in HRAS have been previously described, although this report provides evidence that activating mutations in KRAS or HRAS may cause PPK.

Part I: historical observations and clinical perspectives on the etiology of increased CSF protein levels, CSF clotting, and communicating hydrocephalus: a comprehensive review.
A review of the literature allowed us to conclude that the contiguous deletion of genes RASA1 and MEF2C fulfills the criteria for the diagnosis of a Neurocutaneous syndrome as proposed by Carr et al.[2011].
Both these processes are correlated to the phosphatidylinositol-3-kinase/Akt/mammalian target of rapamycin pathway which is tumorigenesis related in many neoplasms and nearly all phacomatoses.
Neurofibromatosis 1 (NF1), also called von Recklinghausen disease or peripheral NF, is a common autosomal-dominant neurocutaneous disorder associated with mutations of the NF 1 gene.
