Genes affected

DNPH1 (HGNC:21218): (2'-deoxynucleoside 5'-phosphate N-hydrolase 1) This gene was identified on the basis of its stimulation by c-Myc protein. The latter is a transcription factor that participates in the regulation of cell proliferation, differentiation, and apoptosis. The exact function of this gene is not known but studies in rat suggest a role in cellular proliferation and c-Myc-mediated transformation. Two alternative transcripts encoding different proteins have been described. [provided by RefSeq, Jul 2008]

The c.364C>A (p.Q122K) alteration is located in exon 3 (coding exon 3) of the DNPH1 gene. This alteration results from a C to A substitution at nucleotide position 364, causing the glutamine (Q) at amino acid position 122 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
