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.

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 242 of the DRAM2 protein (p.His242Arg). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with DRAM2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1921495). -
