Autosomal recessive hypophosphatemic rickets 1 caused by DMP1 mutation: one pedigree study / 中华内分泌代谢杂志

In the present study, the clinical features of a patient with autosomal recessive hypophosphatemic rickets 1 caused by dentin matrix protein 1(DMP1)gene mutation and her family members were investigated. DMP1 gene from peripheral blood was sequenced by Sanger sequencing, and the known mutation was verified among her family members and 250 healthy populations. The proband was a 42-year-old female with bone deformity of both lower limbs, bone pain, and short stature. The results of X-rays and laboratory examination were consistent with the hypophosphatemic rickets reported before. A homozygous mutation(c.2T> C)in DMP1 was identified by Sanger sequencing in the proband, her son and daughter were heterozygous for c. 2T> C.
