Hereditary hypophosphatemic rickets with hypercalciuria is caused by loss-of-function in the type 2c sodium phosphate cotransporter encoded by the SLC34A3 gene. This report shows a family with a non-previously identified mutation in the SLC34A3 gene and exhibiting mild and different manifestations of HHRH. The probandus had hypophosphatemia, elevated serum 1,25 dihydroxyvitamin D concentrations, high serum alkaline phosphatase levels, hypercalciuria and nephrocalcinosis. The other members of the family presented some of these alterations: the mother, hypercalciuria and high 1,25 dihydroxyvitamin D concentrations; the son, hypercalciuria, high 1,25 dihydroxyvitamin D values and elevated alkaline phosphatases; the father, high alkaline phosphatases. The genetic analysis revealed the existence of a single mutation (G78R) in heterozygosis in the SLC34A3 gene in the probandus, her mother and her brother, but not in the father. These findings suggest that he mutation in heterozygosis likely gave rise to a mild phenotype with different penetrance in the three relatives and also indicates that the elevation of 1,25 dihydroxyvitamin D does not result from hypophosphatemia. Thus, this family raises some issues on the transmission and pathophysiology of hereditary hypophosphatemic rickets with hypercalciuria.<\/jats:p>","DOI":"10.1186\/1750-1172-5-1","type":"journal-article","created":{"date-parts":[[2010,1,14]],"date-time":"2010-01-14T19:15:25Z","timestamp":1263496525000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Genetic and clinical peculiarities in a new family with hereditary hypophosphatemic rickets with hypercalciuria: a case report"],"prefix":"10.1186","volume":"5","author":[{"given":"Natalia","family":"Mejia-Gaviria","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Gil-Pe\u00f1a","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliecer","family":"Coto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa M","family":"P\u00e9rez-Men\u00e9ndez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Santos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2010,1,14]]},"reference":[{"key":"164_CR1","doi-asserted-by":"publisher","first-page":"611","DOI":"10.1056\/NEJM198503073121003","volume":"312","author":"M Tieder","year":"1985","unstructured":"Tieder M, Modai D, Samuel R, Arie R, Halabe A, Bab I, Gabizon D, Liberman UA: Hereditary hypophosphatemic rickets with hypercalciuria.
