Genes affected

DRAM1 (HGNC:25645): (DNA damage regulated autophagy modulator 1) This gene is regulated as part of the p53 tumor suppressor pathway. The gene encodes a lysosomal membrane protein that is required for the induction of autophagy by the pathway. Decreased transcriptional expression of this gene is associated with various tumors. This gene has a pseudogene on chromosome 4. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.137C>T (p.T46M) alteration is located in exon 2 (coding exon 2) of the DRAM1 gene. This alteration results from a C to T substitution at nucleotide position 137, causing the threonine (T) at amino acid position 46 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
