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.

PP5

Variant 1-111120539-C-T is Pathogenic according to our data. Variant chr1-111120539-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 192239.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000204 (297/1457204) while in subpopulation NFE AF = 0.000261 (290/1109732). AF 95% confidence interval is 0.000236. There are 0 homozygotes in GnomAdExome4. There are 146 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change creates a premature translational stop signal (p.Trp165*) in the DRAM2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DRAM2 are known to be pathogenic (PMID: 25983245). This variant is present in population databases (rs201422368, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with retinal dystrophy (PMID: 25983245). ClinVar contains an entry for this variant (Variation ID: 192239). For these reasons, this variant has been classified as Pathogenic. -
