Illumina Laboratory Services, Illumina	RCV001168240	SCV001330816	uncertain significance	Inclusion body myopathy with Paget disease of bone and frontotemporal dementia type 1	2018-01-12	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Labcorp Genetics (formerly Invitae), Labcorp	RCV003769818	SCV004586925	uncertain significance	Frontotemporal dementia and/or amyotrophic lateral sclerosis 6; Inclusion body myopathy with Paget disease of bone and frontotemporal dementia	2024-04-08	criteria provided, single submitter	clinical testing	This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 112 of the VCP protein (p.Lys112Arg). This variant is present in population databases (rs766787045, gnomAD 0.003%). This missense change has been observed in individual(s) with lateral sclerosis diagnosis (Invitae). ClinVar contains an entry for this variant (Variation ID: 914194). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt VCP protein function with a negative predictive value of 80%. 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.
