Thyroid autoantibodies are usually absent in patients with PHP1A, PHP1B or acrodysostosis who have elevated levels of TSH. Endocrinol. N. Engl. Klagge, A., Jessnitzer, B., Pfaeffle, R., Stumvoll, M. & Fuhrer, D. A novel GNAS1 mutation in a German family with Albright’s hereditary osteodystrophy. Endocrinol. Kirnap, M. et al. A multidisciplinary follow-up and early, specific interventions are necessary for efficient therapeutic management of these patients. Metabolic consequences of PHP and related disorders have not been characterized. Ectopic ossification is not calcification and is unrelated to serum levels of calcium and phosphorus. PHP1B was initially defined as isolated resistance to PTH, absence of AHO and normal levels of Gsα activity. Surg. Res.

This form of ectopic calcification is due to elevated levels of the calcium–phosphorus product and hence has not been described in patients with PPHP or POH or those with a mutation in the PRKAR1A or PDE4D genes5,6,8,62,183,184. The term AHO is used to indicate a constellation of physical features originally described by Albright1, including a round face, a stocky habitus with short stature, brachydactyly and ectopic ossification. Weinstein, L. S. et al. The physiological action of PTH on bone is mainly to promote bone resorption, but the extent to which PTH signalling in bone is defective in patients with PHP and related disorders is not completely clear. 97, E863–E867 (2012).

In 1988, elevated blood pressure was reported in 53% of adult patients with PHP and related disorders, with a similar prevalence in clinically defined patients with PHP1A and PHP1B237. Endocrinol.

Tam, V. H. K. et al. It is of interest that in this study, one female patient whose oestrogen production was blocked by GnRH analogues did have evidence of a long-term growth advantage compared with her sister who did not receive the analogues217.

Thiele, S. et al. No data are available on menopause and its timing in women with PHP and related disorders. However, large-scale studies aimed at determining tumour risk in PHP and related disorders have not been carried out. Bone Miner. 27, 639–643 (2005). Physical therapy and meticulous skin care remain the most important conservative approaches to preserve movement and to prevent cutaneous breakdown, respectively251,252. Furthermore, based on the number of AHO features and the extent of ectopic ossifications, patients might be classified as having pseudopseudohypoparathyroidism (PPHP; OMIM #612463), progressive osseous heteroplasia (POH; OMIM #166350) or osteoma cutis. Intragenic GNAS deletion involving exon A/B in pseudohypoparathyroidism type 1 A resulting in an apparent loss of exon A/B methylation: potential for misdiagnosis of pseudohypoparathyroidism type 1B. Establishing the correct diagnosis in patients with PHP, PPHP, POH or acrodysostosis allows an appropriate conversation to take place with patients and families, including anticipatory guidance, and informs decisions on biochemical screening and treatment of potential endocrine defects. 60, 231–236 (2013).
