Genes affected

PITRM1 (HGNC:17663): (pitrilysin metallopeptidase 1) The protein encoded by this gene is an ATP-dependent metalloprotease that degrades post-cleavage mitochondrial transit peptides. The encoded protein binds zinc and can also degrade amyloid beta A4 protein, suggesting a possible role in Alzheimer's disease. [provided by RefSeq, Dec 2016]

The c.2599G>A (p.V867M) alteration is located in exon 23 (coding exon 23) of the PITRM1 gene. This alteration results from a G to A substitution at nucleotide position 2599, causing the valine (V) at amino acid position 867 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 768 of the PITRM1 protein (p.Val768Met). This variant is present in population databases (rs371412408, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PITRM1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
