Genes affected

TUT1 (HGNC:26184): (terminal uridylyl transferase 1, U6 snRNA-specific) This gene encodes a nucleotidyl transferase that functions as both a terminal uridylyltransferase and a nuclear poly(A) polymerase. The encoded enzyme specifically adds and removes nucleotides from the 3' end of small nuclear RNAs and select mRNAs and may function in controlling gene expression and cell proliferation.[provided by RefSeq, Apr 2009]

The c.2042G>A (p.R681Q) alteration is located in exon 9 (coding exon 9) of the TUT1 gene. This alteration results from a G to A substitution at nucleotide position 2042, causing the arginine (R) at amino acid position 681 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
