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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2022The c.568C>T (p.R190W) 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 568, causing the arginine (R) at amino acid position 190 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
