Genes affected

IMPA2 (HGNC:6051): (inositol monophosphatase 2) This locus encodes an inositol monophosphatase. The encoded protein catalyzes the dephosphoylration of inositol monophosphate and plays an important role in phosphatidylinositol signaling. This locus may be associated with susceptibility to bipolar disorder. [provided by RefSeq, Jan 2011]

Ambry Genetics

Nov 30, 2022

The c.428C>T (p.T143M) alteration is located in exon 5 (coding exon 5) of the IMPA2 gene. This alteration results from a C to T substitution at nucleotide position 428, causing the threonine (T) at amino acid position 143 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
