Genes affected

DROSHA (HGNC:17904): (drosha ribonuclease III) This gene encodes a ribonuclease (RNase) III double-stranded RNA-specific ribonuclease and subunit of the microprocessor protein complex, which catalyzes the initial processing step of microRNA (miRNA) synthesis. The encoded protein cleaves the stem loop structure from the primary microRNA (pri-miRNA) in the nucleus, yielding the precursor miRNA (pre-miRNA), which is then exported to the cytoplasm for further processing. In a human cell line lacking a functional copy of this gene, canonical miRNA synthesis is reduced. Somatic mutations in this gene have been observed in human patients with kidney cancer.

The c.3196C>T (p.R1066C) alteration is located in exon 26 (coding exon 24) of the DROSHA gene. This alteration results from a C to T substitution at nucleotide position 3196, causing the arginine (R) at amino acid position 1066 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
