C	C107377	Musculoskeletal Disorder	Musculoskeletal System Disorder	Disorder of Musculoskeletal System	A non-neoplastic or neoplastic disorder that affects muscles and bones.		C2991	Disease or Disorder			C99147	Neonatal Research Network Terminology		
C	C99068	Pulmonary Surfactant Metabolism Dysfunction-1	Surfactant Protein B Deficiency	Surfactant Apoprotein B Deficiency	An autosomal recessive condition caused by mutation(s) in the SFTPB gene, encoding pulmonary surfactant-associated protein B. It is characterized by severe respiratory distress-like illness and responds poorly to exogenous administration of surfactant.

C	C2989	22q11.2 Deletion Syndrome	22q Deletion Syndrome(s)	DGS1 || DiGeorge Sequence || DiGeorge Syndrome || DiGeorge Syndrome Type 1 || Shprintzen Syndrome	A congenital anomaly characterized by immunodeficiency, abnormal facies, congenital heart disease, hypocalcemia, and increased susceptibility to infections. Pathologic characteristics include conotruncal abnormalities and absence or hypoplasia of thymus and parathyroid glands. DiGeorge syndrome is associated with abnormalities of chromosome 22. Also known as DiGeorge anomaly.	A group of phenotypically variable, mostly sporadic conditions caused by 1.5- to 3.0-Mb hemizygous deletions of chromosome 22q11.2. Haploinsufficiency of the TBX1 gene encoding the transcription factor T-box 1 is believed responsible for most of the physical findings. Clinical features may include cardiac anomalies, including truncus arteriosus and tetralogy of Fallot, as well as other anomalies, including micrognathia, thymic aplasia (with resultant immunodeficiency), cleft palate, and hypoparathyroidism.

C	C3222	Medulloblastoma	Medulloblastoma		A malignant, invasive embryonal neoplasm arising from the cerebellum or posterior fossa. It occurs predominantly in children and has the tendency to metastasize via the cerebrospinal fluid pathways. Signs and symptoms include truncal ataxia, disturbed gait, lethargy, headache, and vomiting. There are four histologic variants: classic medulloblastoma, large cell/anaplastic medulloblastoma, desmoplastic/nodular medulloblastoma, and medulloblastoma with extensive nodularity.	A rapidly progressive cancer of the brain that originates in the cerebellum.	C3268	Nervous System Neoplasm			C99147	Neonatal Research Network Terminology		
C	C61259	Mucopolysaccharidosis	Mucopolysaccharidosis		A group of autosomal recessive or X-linked inherited lysosomal storage disorders affecting the metabolism of mucopolysaccharides, resulting in the accumulation of mucopolysaccharides in the body. Signs and symptoms include organomegaly, intellectual disabilities, abnormal skeletal development, heart disorders, hearing loss, and central nervous system deficiencies.

C	C9305	Malignant Neoplasm	Cancer	Malignancy || Malignant Growth || Malignant Neoplasm || Malignant Neoplastic Disease	A tumor composed of atypical neoplastic, often pleomorphic cells that invade other tissues. Malignant neoplasms often metastasize to distant anatomic sites and may recur after excision. The most common malignant neoplasms are carcinomas, Hodgkin and non-Hodgkin lymphomas, leukemias, melanomas, and sarcomas.	Uncontrolled growth of abnormal cells with potential for metastatic spread.
