Prevalence and Significance of Mutations in Genes Encoding NaPi-co-transporters in the Development of CAVD
Mutations in the SLC34A2 gene, that encodes the sodium phosphate co-transporter (NaPi-IIb), cause defect cell-uptake of phosphate, which leads to formation of calcium-phosphate concretions in the lungs as seen in Pulmonary…
