title: The first mutation identified in a Chinese acrodysostosis patient confirms a p.G289E variation of PRKAR1A causes acrodysostosis.
abstract: Acrodysostosis is a rare skeletal dysplasia, which has not been reported previously in patients of Chinese origin. The PRKAR1A gene and PDE4D gene have been found to be causative genes of acrodysostosis. A Chinese girl with acrodysostosis and concomitant multiple hormone resistance was recruited for our study. Clinical and biochemical characters were analyzed. DNA was extracted from leukocytes and was sequenced for GNAS, PDE4D and PRKAR1A gene mutations. A de novo heterozygous missense mutation (c.866G>A/p.G289E) was identified in the PRKAR1A gene. This mutation coincided with a mutation that had been found in a patient from another ethnic group. Our findings further suggest that the c.866G>A/p.G289E mutation in the PRKAR1A gene may be the cause of acrodysostosis with concomitant multiple hormone resistance. Moreover, it is the first report of acrodysostosis genetic analysis of Chinese origin.
