Genes affected

PRM1 (HGNC:9447): (protamine 1) Predicted to enable DNA binding activity. Predicted to be involved in DNA packaging. Predicted to act upstream of or within nucleus organization and spermatid development. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

PRM1 links:

RMI2 (HGNC:28349): (RecQ mediated genome instability 2) RMI2 is a component of the BLM (RECQL3; MIM 604610) complex, which plays a role in homologous recombination-dependent DNA repair and is essential for genome stability (Xu et al., 2008 [PubMed 18923082]).[supplied by OMIM, Nov 2008]

Ambry Genetics

Oct 12, 2021

The c.74G>A (p.R25Q) alteration is located in exon 1 (coding exon 1) of the PRM1 gene. This alteration results from a G to A substitution at nucleotide position 74, causing the arginine (R) at amino acid position 25 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
