Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SLC34A3 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: May be involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane. Probably mediates 20-30% of the apical influx.
• Disease: DISEASE: Hereditary hypophosphatemic rickets with hypercalciuria (HHRH) [MIM:241530]: Autosomal recessive form of hypophosphatemia characterized by reduced renal phosphate reabsorption and rickets. Increased serum levels of 1,25-dihydroxyvitamin D lead to increase in urinary calcium excretion. {ECO:0000269|PubMed:16358214, ECO:0000269|PubMed:16358215}. Note=The disease is caused by mutations affecting the gene represented in this entry.
• Pathway: Transport of inorganic cations/anions and amino acids/oligopeptides;SLC-mediated transmembrane transport;Transport of small molecules;Type II Na+/Pi cotransporters;Sodium-coupled phosphate cotransporters (Consensus)
