Noonan syndrome
Syndromic craniosynostoses [DS:H00458]
Noonan syndrome and related disorders [DS:H00523]
Noonan syndrome (NS) is an autosomal dominant disorder characterised by short stature, craniofacial dysmorphism, congenital cardiac defects, cryptorchidism in men, coagulation defects, and neurocognitive delay. In addition, individuals with NS have an increased risk of developing cancer. NS is caused by germline mutations in genes that encode components or regulators of the Ras/MAPK pathway. Heterozygous, pathogenic variants in 9 known genes account for approximately 80% of cases. The most common gene associated with NS is PTPN11, which accounts for approximately 50% of all cases.
