Loss of muscle. What causes neurofibromatosis? Neurofibromatosis (NF) occurs as a result of defects in different genes. Nearly half of the cases of NF are inherited, whereas the other half is caused by a spontaneous mutation of the gene. Neurofibromatosis type 1 (NF1) is caused by mutation ...
The cutaneous pattern in the mother of case 1 was clearly segmental, and probably represents mosaicism for the NF1 mutation which was passed on to the child. In the second case the distribution in the mother was less obviously segmental, but may still represent mosaicism. It is more difficult...
Approximately 75% of GISTs harbor a KIT gene mutation, and these mutations lead to constitutive activation of the kinase. KIT is a member of the type III receptor tyrosine kinase family that includes platelet-derived growth factor receptors-a and -b (PDGFRA and PDGFRB), as well as the ...
What is an autosomal dominant mutation? How do autosomal dominant and autosomal recessive pedigrees differ? Is BRCA1 autosomal dominant or recessive? How can genetic disorders be autosomal dominant and autosomal recessive? How many JLNS are autosomal dominant?
Fig. 1 Schematic representation of the overlap between tumor type, TERT promoter, and TP53 mutation. TERT promoter mutation is a powerful marker of poor prognosis irrespective of tumor histotype. TP53 mutation is associated with high mutation burden but the correlation with poor prognosis is not in...
Pediatric multidisciplinary (MD) care has improved life expectancy, however, transfer to internal medicine is hindered by the lack of adequate MD care for adults. We have launched an MD outpatient clinic providing syndrome-specific care for adults with CRGS, which, to our knowledge, is the first...

LOH is strongly associated with loss of the wild-type allele in individuals with an inherited cancer predisposition syndrome and carry a germline mutation in genes such as RB1 in retinoblastoma or BRCA1 in breast and ovarian cancer [2, 3]. This “second hit” hypothesis was initially proposed...
RAF is a family of kinases activated by RAS that participate in the mitogen-activated protein kinase (MAPK) cascade. Fig. 1 summarizes the RAS pathway and demonstrates (potential) opportunities to target the cascade. The properties of each KRAS mutation were then combined to generate a prediction...
[27]. Other early-onset retinal dystrophies can give a similar clinical picture as LCA. However, the visual function in other early-onset retinal dystrophies is usually better, depending on the underlying gene and mutation [25] and may also be part of a syndromic presentation. Advanced stages...
