" /> Acrodysostosis 1 with or without hormone resistance - CISMeF





Preferred Label : Acrodysostosis 1 with or without hormone resistance;

Symbol : ACRDYS1;

CISMeF acronym : ACRDYS1; ADOHR;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : ADOHR;

Description : Acrodysostosis-1 is a form of skeletal dysplasia characterized by short stature, severe brachydactyly, facial dysostosis, and nasal hypoplasia. Affected individuals often have advanced bone age and obesity. Laboratory studies show resistance to multiple hormones, including parathyroid, thyrotropin, calcitonin, growth hormone-releasing hormone, and gonadotropin (summary by Linglart et al., 2011). However, not all patients show endocrine abnormalities (Lee et al., 2012). See also ACRDYS2 (614613), caused by mutation in the PDE4D gene (600129) on chromosome 5q12.;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the cAMP-dependent regulatory subunit 1 of protein kinase A gene (PRKAR1A, 188830.0015);

Laboratory abnormalities : Increased serum parathyroid hormone; Low or normal serum calcium; Normal or increased serum phosphate; Increased urinary cAMP excretion; Increased serum thyrotropin; Increased serum calcitonin;

Prefixed ID : #101800;
