Function

Disease associations

• Leukemia, juvenile myelomonocyticJMML

  An aggressive pediatric myelodysplastic syndrome/myeloproliferative disorder characterized by malignant transformation in the hematopoietic stem cell compartment with proliferation of differentiated progeny. Patients have splenomegaly, enlarged lymph nodes, rashes, and hemorrhages.

• Noonan syndrome 6NS6

  A form of Noonan syndrome, a disease characterized by short stature, facial dysmorphic features such as hypertelorism, a downward eyeslant and low-set posteriorly rotated ears, and a high incidence of congenital heart defects and hypertrophic cardiomyopathy. Other features can include a short neck with webbing or redundancy of skin, deafness, motor delay, variable intellectual deficits, multiple skeletal defects, cryptorchidism, and bleeding diathesis. Individuals with Noonan syndrome are at risk of juvenile myelomonocytic leukemia, a myeloproliferative disorder characterized by excessive production of myelomonocytic cells.

• RAS-associated autoimmune leukoproliferative disorderRALD

  A disorder of apoptosis, characterized by chronic accumulation of non-malignant lymphocytes, defective lymphocyte apoptosis, and an increased risk for the development of hematologic malignancies.

• Melanocytic nevus syndrome, congenitalCMNS

  A syndrome characterized by congenital pigmentary skin lesions which can occur at any site and can cover most of the body surface. These lesions may or may not be hairy. Congenital melanocytic nevi are associated with neuromelanosis (the presence of melanin-producing cells within the brain parenchyma or leptomeninges). Less commonly they are associated with malignant melanoma in childhood, both in the skin and the central nervous system. CMNS patients also tend to have a characteristic facial appearance, including wide or prominent forehead, periorbital fullness, small short nose with narrow nasal bridge, round face, full cheeks, prominent premaxilla, and everted lower lip.

• Melanosis, neurocutaneousNCMS

  A rare congenital disease characterized by the presence of giant or multiple melanocytic nevi on the skin, foci of melanin-producing cells within the brain parenchyma, and infiltration of leptomeninges by abnormal melanin deposits. Neurologic abnormalities include seizures, hydrocephalus, arachnoid cysts, tumors, and syringomyelia. Some patients may develop malignant melanoma.

• Keratinocytic non-epidermolytic nevusKNEN

  Epidermal nevi of the common, non-organoid and non-epidermolytic type are benign skin lesions and may vary in their extent from a single (usually linear) lesion to widespread and systematized involvement. They may be present at birth or develop early during childhood.

• Thyroid cancer, non-medullary, 2NMTC2

  A form of non-medullary thyroid cancer (NMTC), a cancer characterized by tumors originating from the thyroid follicular cells. NMTCs represent approximately 95% of all cases of thyroid cancer and are classified into papillary, follicular, Hurthle cell, and anaplastic neoplasms.
