Immunodeficiency, and Pheochromocytoma

Rubinstein-Taybi syndrome is a multiple congenital anomaly syndrome characterized by mental retardation, postnatal growth deficiency, microcephaly, broad thumbs and halluces, and dysmorphic facial features. The facial appearance is striking, with highly arched eyebrows, long eyelashes, downslanting palpebral fissures, broad nasal bridge, beaked nose with the nasal septum, highly arched palate, mild micrognathia, and characteristic grimacing or abnormal smile. Affected individuals also have an increased risk of tumor formation (Rubinstein and Taybi, 1963; review by Hennekam, 2006).Floating-Harbor syndrome (OMIM ), which shows phenotypic overlap with Rubinstein-Taybi syndrome, is caused by mutation in the SRCAP gene (OMIM ), a coactivator for CREBBP. Genetic Heterogeneity of Rubinstein-Taybi SyndromeRubinstein-Taybi syndrome-1 (RSTS1) constitutes about 50 to 70% of patients with the disorder. Rubinstein-Taybi syndrome-2 (RSTS2 ) comprises about 3% of patients and is primarily due to de novo heterozygous mutation in the EP300 gene (OMIM ) on chromosome 22q13 (Bartsch et al., 2010).See also chromosome 16p13.3 deletion syndrome (OMIM ), a severe form of Rubinstein-Taybi syndrome resulting from a contiguous gene deletion involving the CREBBP gene as well as other neighboring genes.

Cushing disease (CD) is the most common cause of endogenous Cushing syndrome (CS; see this term) and is due to pituitary chronic over-secretion of ACTH by a pituitary corticotroph adenoma.

ACTH-independent macronodular adrenal hyperplasia (AIMAH) is an endogenous form of adrenal Cushing syndrome characterized by multiple bilateral adrenocortical nodules that cause a striking enlargement of the adrenal glands. Although some familial cases have been reported, the vast majority of AIMAH cases are sporadic. Patients typically present in the fifth and sixth decades of life, approximately 10 years later than most patients with other causes of Cushing syndrome (Swain et al., 1998; Christopoulos et al., 2005).Approximately 10 to 15% of adrenal Cushing syndrome is due to primary bilateral ACTH-independent adrenocortical pathology. The 2 main subtypes are AIMAH and primary pigmented nodular adrenocortical disease (PPNAD, see {610489}), which is often a component of the Carney complex (OMIM ) and associated with mutations in the PRKAR1A gene (OMIM ) on chromosome 17q23-q24. AIMAH is rare, representing less than 1% of endogenous causes of Cushing syndrome (Swain et al., 1998; Christopoulos et al., 2005).See also ACTH-independent Cushing syndrome (OMIM ) due to somatic mutation in the PRKACA gene (OMIM ).Cushing 'disease' (OMIM ) is an ACTH-dependent disorder caused in most cases by pituitary adenomas that secrete excessive ACTH. Genetic Heterogeneity of ACTH-Independent Macronodular Adrenal HyperplasiaAIMAH2 (OMIM ) is caused by germline mutation of 1 allele of the ARMC5 gene (OMIM ) coupled with a somatic mutation in the other allele.

Common variable immunodeficiency-8 with autoimmunity is an autosomal recessive disorder of immune dysregulation. Affected individuals have early childhood onset of recurrent infections, particularly respiratory infections, and also develop variable autoimmune disorders, including idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, and inflammatory bowel disease. The presentation and phenotype are highly variable, even within families (summary by Lopez-Herrera et al., 2012 and Alangari et al., 2012). Immunologic findings are also variable and may include decreased B cells, hypogammaglobulinemia, and deficiency of CD4+ T regulatory (Treg) cells (Charbonnier et al., 2015).For a general description and a discussion of genetic heterogeneity of common variable immunodeficiency, see CVID1 (OMIM ).
