Genes affected
NTPCR (HGNC:28204): (nucleoside-triphosphatase, cancer-related) The protein encoded by this gene is a non-specific nucleoside triphosphatase that is slow-acting in vitro. This gene is overexpressed in many tumor tissues, and while it is not essential for the cell, overexpression is cytotoxic. However, the cytotoxicity is not related to its triphosphatase activity.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 05, 2022The c.548C>T (p.T183M) alteration is located in exon 5 (coding exon 5) of the NTPCR gene. This alteration results from a C to T substitution at nucleotide position 548, causing the threonine (T) at amino acid position 183 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
