Sequence analysis of <i>PHEX</i> in patients with hereditary hypophosphatemia.

<p>(A) Five novel <i>PHEX</i> mutations. c.983_987dupCTACC (patient II-3 and her mother) and c.436+1G>T (patient IX-3 and his mother) are inherited mutations from mother; c.1586+2T>G (patinet IV-3), c.1206delA (patient XV-3), and c.1217G>T (patientVI-3) are de novo mutations not present in parents. The c.1586+2T>G results in exon 14 skipping. (B) Six previously reported <i>PHEX</i> mutations. c.1645C>T, c. 187+1G>T, and c.2104C>T are de novo mutations. c.1601C>T, c.2239C>T, and c.1404+1del G are inherited mutations transmitted from mother. Mutation is indicated by an arrow.
