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]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.3010G>A (p.A1004T) alteration is located in exon 26 (coding exon 26) of the PITRM1 gene. This alteration results from a G to A substitution at nucleotide position 3010, causing the alanine (A) at amino acid position 1004 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 905 of the PITRM1 protein (p.Ala905Thr). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with PITRM1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2077496). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
