Genes affected

PURG (HGNC:17930): (purine rich element binding protein G) The exact function of this gene is not known, however, its encoded product is highly similar to purine-rich element binding protein A. The latter is a DNA-binding protein which binds preferentially to the single strand of the purine-rich element termed PUR, and has been implicated in the control of both DNA replication and transcription. This gene lies in close proximity to the Werner syndrome gene, but on the opposite strand, on chromosome 8p11. [provided by RefSeq, Apr 2016]

Ambry Genetics

Nov 29, 2023

The c.818G>A (p.R273K) alteration is located in exon 1 (coding exon 1) of the PURG gene. This alteration results from a G to A substitution at nucleotide position 818, causing the arginine (R) at amino acid position 273 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
