Genes affected

BCDIN3D (HGNC:27050): (BCDIN3 domain containing RNA methyltransferase) This gene encodes an RNA methyltransferase which belongs to the rossmann fold methyltransferase family, and serves as a 5'-methylphosphate capping enzyme that is specific for cytoplasmic histidyl tRNA. The encoded protein contains an S-adenosylmethionine binding domain and uses the methyl group donor, S-adenosylmethionine. This gene is overexpressed in breast cancer cells, and is related to the tumorigenic phenotype and poor prognosis of breast cancer. The encoded protein is thought to promote the cellular invasion of breast cancer cells, by downregulating the expression of tumor suppressor miRNAs through the dimethylation of the 5-monophosphate of the corresponding precursor miRNAs.

The c.236A>G (p.D79G) alteration is located in exon 2 (coding exon 2) of the BCDIN3D gene. This alteration results from a A to G substitution at nucleotide position 236, causing the aspartic acid (D) at amino acid position 79 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
