Genes affected

TUT4 (HGNC:28981): (terminal uridylyl transferase 4) Enables RNA uridylyltransferase activity. Involved in RNA metabolic process; negative regulation of transposition, RNA-mediated; and stem cell population maintenance. Located in cytoplasmic ribonucleoprotein granule; cytosol; and nucleolus. Implicated in liver benign neoplasm. Biomarker of breast cancer. [provided by Alliance of Genome Resources, Apr 2022]

The c.4927G>T (p.V1643L) alteration is located in exon 30 (coding exon 29) of the ZCCHC11 gene. This alteration results from a G to T substitution at nucleotide position 4927, causing the valine (V) at amino acid position 1643 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
