| Outline of Final Research Achievements |
We investigated the genetic backgrounds of heterotopic ossification in patients with POH overlapped with PHPⅠa (two patients) or PPHP (one patient). The de novo mutations in GNAS gene were detected in all three patients. RT-PCR method and SNP analyses showed that one mutation(POH/PHPⅠa) was on the maternal allele and the other two mutations were on the paternal allele. DNA methylation abnormalities were not detected. These data suggested that GNAS mutation on the maternal allele could cause heterotopic ossification.
