Patients & methods A total of 265 patients with different gastric diseases were collected. ELISA was to detect sPGC and anti-H. pylori IgG. LncRNAs was determined by qRT-PCR. Results The area under receiver operating characteristic curve of lncRNAs in discriminating GC+AG (atrophic gastritis) and superficial gastritis (SG) were 79.0, 68.1 and 75.9%. The diagnostic performance of lncRNAs with sPGC had increasing trends in distinguishing GC from non-GC, SG from GC+AG comparing with lncRNAs, with no statistic difference. Diagnosis efficacies of lncRNAs with anti-H. pylori IgG improved dramatically. Conclusions Serum lncRNAs could distinguish GC, AG and SG. Diagnosis efficiencies of lncRNAs with sPGC and anti-H. pylori-IgG could be improved.VRK1 encodes a serine/protein kinase possibly involved in pathways related to amyotrophic lateral sclerosis (ALS) pathogenesis. Pathogenic variants in VRK1 have been related to different phenotypes. We describe the clinical phenotype of two unrelated Portuguese patients with different VRK1 variants. Both patients presented a bilateral distal weakness in lower limbs beginning in childhood slowly progressing to upper limbs, associated with pyramidal signs, without bulbar, respiratory or cognitive involvement, according to probable ALS. Imaging and nerve conduction studies were unremarkable in both patients. Genetic testing in patient 1 identified two VRK1 variants in heterozygosity c.265C > T, p.(Arg89*) and c.769G > A, p.(Gly257Ser), classified as pathogenic and variant of uncertain significance, respectively. In patient 2, two probably pathogenic variants in VRK1 were identified in heterozygosity c.71014T > C in intron 8 and c.721C > T, p.(Arg241Cys) in exon 9. We report two
