Genes affected

DIDO1 (HGNC:2680): (death inducer-obliterator 1) Apoptosis, a major form of cell death, is an efficient mechanism for eliminating unwanted cells and is of central importance for development and homeostasis in metazoan animals. In mice, the death inducer-obliterator-1 gene is upregulated by apoptotic signals and encodes a cytoplasmic protein that translocates to the nucleus upon apoptotic signal activation. When overexpressed, the mouse protein induced apoptosis in cell lines growing in vitro. This gene is similar to the mouse gene and therefore is thought to be involved in apoptosis. Alternatively spliced transcripts have been found for this gene, encoding multiple isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0031928718).
• BP6: Variant 20-62881068-C-T is Benign according to our data. Variant chr20-62881068-C-T is described in ClinVar as [Benign]. Clinvar id is 733406.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00138 (211/152350) while in subpopulation EAS AF= 0.0264 (137/5180). AF 95% confidence interval is 0.0228. There are 1 homozygotes in gnomad4. There are 109 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 211 AD gene.
