Variant summary

Our verdict is The variant received -7 classification points (ACMG Germline Pathogenicity v2019). PM2_SupportingBP4_StrongBP6_Strong

The NM_025077.4(TOE1):c.-44T>C variant causes a 5 prime UTR change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.00000248 (AC=4) in the gnomAD database across 1,613,674 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000193. In-silico predictor (AlphaMissense) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★★).

Genes affected

TOE1 (HGNC:15954): (target of EGR1, exonuclease) Enables poly(A)-specific ribonuclease activity and snRNA binding activity. Involved in RNA phosphodiester bond hydrolysis, exonucleolytic and snRNA 3'-end processing. Located in Cajal body and cytoplasm. Implicated in pontocerebellar hypoplasia type 7.

TOE1 links:

MUTYH (HGNC:7527): (mutY DNA glycosylase) This gene encodes a DNA glycosylase involved in oxidative DNA damage repair. The enzyme excises adenine bases from the DNA backbone at sites where adenine is inappropriately paired with guanine, cytosine, or 8-oxo-7,8-dihydroguanine, a major oxidatively damaged DNA lesion. The protein is localized to the nucleus and mitochondria. This gene product is thought to play a role in signaling apoptosis by the introduction of single-strand breaks following oxidative damage. Mutations in this gene result in heritable predisposition to colorectal cancer, termed MUTYH-associated polyposis (MAP). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2017]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript

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

PM2

Rare in gnomAD for AR/unknown gene (popmax AF below threshold) — PM2 Supporting; GnomAD popmax AF = 0.000193 — borderline rare for AR gene (threshold 0.001) — PM2 supporting.

BP4

Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).

BP6

ClinVar 2-star benign — strong (BP6); ClinVar germline classification: Benign/Likely Benign, 2 star(s).
