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]

Ambry Genetics

Apr 18, 2023

The c.1937C>T (p.P646L) alteration is located in exon 9 (coding exon 9) of the TUT1 gene. This alteration results from a C to T substitution at nucleotide position 1937, causing the proline (P) at amino acid position 646 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
