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]

ENSG00000255508 (HGNC:):

ACMG classification
