Genes affected
BPNT1 (HGNC:1096): (3'(2'), 5'-bisphosphate nucleotidase 1) BPNT1, also called bisphosphate 3-prime-nucleotidase, or BPntase, is a member of a magnesium-dependent phosphomonoesterase family. Lithium, a major drug used to treat manic depression, acts as an uncompetitive inhibitor of BPntase. The predicted human protein is 92% identical to mouse BPntase. BPntase's physiologic role in nucleotide metabolism may be regulated by inositol signaling pathways. The inhibition of human BPntase may account for lithium-induced nephrotoxicity.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.155G>A (p.R52Q) alteration is located in exon 3 (coding exon 2) of the BPNT1 gene. This alteration results from a G to A substitution at nucleotide position 155, causing the arginine (R) at amino acid position 52 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
