Genes affected

LONP1 (HGNC:9479): (lon peptidase 1, mitochondrial) This gene encodes a mitochondrial matrix protein that belongs to the Lon family of ATP-dependent proteases. This protein mediates the selective degradation of misfolded, unassembled or oxidatively damaged polypeptides in the mitochondrial matrix. It may also have a chaperone function in the assembly of inner membrane protein complexes, and participate in the regulation of mitochondrial gene expression and maintenance of the integrity of the mitochondrial genome. Decreased expression of this gene has been noted in a patient with hereditary spastic paraplegia (PMID:18378094). Alternatively spliced transcript variants have been found for this gene.

The c.2853G>C (p.Q951H) alteration is located in exon 18 (coding exon 18) of the LONP1 gene. This alteration results from a G to C substitution at nucleotide position 2853, causing the glutamine (Q) at amino acid position 951 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
