Nephrolithiasis/osteoporosis, hypophosphatemic, 1
Hypophosphatemic nephrolithiasis/osteoporosis-1 is an autosomal dominant disorder caused by mutations of the SLC34A1 gene. The hypophosphatemia is the result of excessive renal phosphorous loss. Hypopphosphatemia and Hyperphosphaturia cause osteoporosis and nephrocalcinosis, respectively.
Hyperphosphaturia results in osteoporosis and nephrocalcinossis.
Renal calcium wastage is responsible for osteoporosis and nephrocalcinosis.
Nephrocalcinosis is the result of excessive renal wastage of calcium and phosphate.
Osteoporosis is the result of excessive renal wastage of calcium and phosphate.
