What is the official name of the RMRP gene?
The official name of this gene is “RNA component of mitochondrial RNA processing endoribonuclease.”
RMRP is the gene's official symbol. The RMRP gene is also known by other names, listed below.

What is the normal function of the RMRP gene?
Unlike many genes, the RMRP gene does not contain instructions for making a protein. Instead, a molecule called a noncoding RNA, a chemical cousin of DNA, is produced from the RMRP gene. This RNA attaches (binds) to several proteins, forming an enzyme called mitochondrial RNA-processing endoribonuclease, or RNase MRP.
The RNase MRP enzyme is thought to be involved in several important processes in the cell. For example, it likely helps copy (replicate) the DNA found in the energy-producing centers of cells (mitochondria). The RNase MRP enzyme probably also processes ribosomal RNA, which is required for assembling protein building blocks (amino acids) into functioning proteins. In addition, this enzyme helps control the cell cycle, which is the cell's way of replicating itself in an organized, step-by-step fashion.
Does the RMRP gene share characteristics with other genes?
The RMRP gene belongs to a family of genes called small miscellaneous ncRNAs (small miscellaneous ncRNAs).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.

Where is the RMRP gene located?
Cytogenetic Location: 9p21-p12
Molecular Location on chromosome 9: base pairs 35,657,750 to 35,658,017
The RMRP gene is located on the short (p) arm of chromosome 9 between positions 21 and 12.
More precisely, the RMRP gene is located from base pair 35,657,750 to base pair 35,658,017 on chromosome 9.
