Genes affected

DRAM2 (HGNC:28769): (DNA damage regulated autophagy modulator 2) The protein encoded by this gene binds microtubule-associated protein 1 light chain 3 and is required for autophagy. Defects in this gene are a cause of retinal dystrophy. In addition, two microRNAs (microRNA 125b-1 and microRNA 144) can bind to the mRNA of this gene and produce the disease state.

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a chain DNA damage-regulated autophagy modulator protein 2 (size 265) in uniprot entity DRAM2_HUMAN there are 8 pathogenic changes around while only 2 benign (80%) in ENST00000484310.6
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.992
• PP5: Variant 1-111120671-T-A is Pathogenic according to our data. Variant chr1-111120671-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 192237.Status of the report is criteria_provided_single_submitter, 1 stars.
