Genes affected

PARL (HGNC:18253): (presenilin associated rhomboid like) This gene encodes a member of the rhomboid family of intramembrane serine proteases that is localized to the inner mitochondrial membrane. The encoded protein regulates mitochondrial remodeling and apoptosis through regulated substrate proteolysis. Proteolytic processing of the encoded protein results in the release of a small peptide, P-beta, which may transit to the nucleus. Mutations in this gene may be associated with Parkinson's disease.

The c.593C>T (p.S198L) alteration is located in exon 5 (coding exon 5) of the PARL gene. This alteration results from a C to T substitution at nucleotide position 593, causing the serine (S) at amino acid position 198 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
