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.

The c.410T>C (p.I137T) alteration is located in exon 6 (coding exon 5) of the BPNT1 gene. This alteration results from a T to C substitution at nucleotide position 410, causing the isoleucine (I) at amino acid position 137 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
