While patients with PRKAR1A mutations (referred to as ACRDYS type 1) constantly present with significant hormonal resistance, hormonal resistance in patients with PDE4D mutations (referred to as ACRDYS type 2) is rare, and when present, is relatively [orpha.net]

Two PRKAR1A patients each with a novel mutation presented a specific pattern of brachydactyly. One PDE4D patient presented with acroskyphodysplasia. Additional phenotypic differences included mental retardation in PDE4D patients. [ncbi.nlm.nih.gov]

• Suggestibility

  A girl, who presented initially to the orthodontist because of anterior and posterior open-bite, was noted to have short stature and facial dysmorphism suggesting the diagnosis of acrodysostosis. Her father had similar features, though less marked. [ncbi.nlm.nih.gov]

• Confusion

  Because of the hormone resistance that would accompany, acrodysostosis can be confused with pseudohypoparathyroidism. Mutations of PRKAR1A and PDE4D are reported to be responsible for the disease in less than 50 cases. [abstracts.eurospe.org]

Genetic workup included nondiagnostic chromosomal microarray and skeletal dysplasia molecular panels. These clinical findings are different from any recognized form of acrodysostosis syndrome. [onlinelibrary.wiley.com]

Clinical Testing and Workup Prenatal fetal ultrasonography, an exam in which reflected sound waves create an image of the developing fetus, may potentially reveal intrauterine growth retardation and short long bones that are compatible with the diagnosis [rarediseases.org]

Management and treatment There is no specific treatment for acrodysostosis. [orpha.net]

Treatment - Acrodysostosis There are no standardized treatment protocols or guidelines for affected individuals. Due to the rarity of the disease, there are no treatment trials that have been tested on a large group of patients. [checkorphan.org]

Standard Therapies Treatment The treatment of acrodysostosis is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. [rarediseases.org]

The future of treatment There is currently no typical approach to treatment. [acrodysostosis.org]

Treatment: No specific treatment for acrodysostosis exist, up to date. Nevertheless, hormonal resistances, in particular to PTH and TSH, can be treated appropriately as in any other form of hypoparathyroidism and hypothyroidism. [iofbonehealth.org]
