Genes affected

GPX2 (HGNC:4554): (glutathione peroxidase 2) The protein encoded by this gene belongs to the glutathione peroxidase family, members of which catalyze the reduction of organic hydroperoxides and hydrogen peroxide (H2O2) by glutathione, and thereby protect cells against oxidative damage. Several isozymes of this gene family exist in vertebrates, which vary in cellular location and substrate specificity. This isozyme is predominantly expressed in the gastrointestinal tract (also in liver in human), is localized in the cytoplasm, and whose preferred substrate is hydrogen peroxide. Overexpression of this gene is associated with increased differentiation and proliferation in colorectal cancer. This isozyme is also a selenoprotein, containing the rare amino acid selenocysteine (Sec) at its active site. Sec is encoded by the UGA codon, which normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated the Sec insertion sequence (SECIS) element, that is necessary for the recognition of UGA as a Sec codon, rather than as a stop signal. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2016]

GPX2 links:

CHURC1-FNTB (HGNC:42960): (CHURC1-FNTB readthrough) This locus represents naturally occurring read-through transcription between the neighboring CHURC1 (churchill domain containing 1) and FNTB (farnesyltransferase, CAAX box, beta) on chromosome 14. The read-through transcript produces a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Feb 2011]

CHURC1 (HGNC:20099): (churchill domain containing 1) Predicted to enable zinc ion binding activity. Predicted to be involved in positive regulation of transcription, DNA-templated. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, Cadd, Dann, Eigen, FATHMM_MKL, phyloP100way_vertebrate, PROVEAN [when BayesDel_addAF, BayesDel_noAF, max_spliceai, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.006166607).

BS2

High Homozygotes in GnomAd4 at 13 AR gene
