Genes affected

TENT4A (HGNC:16705): (terminal nucleotidyltransferase 4A) The protein encoded by this gene is a DNA polymerase that is likely involved in DNA repair. In addition, the encoded protein may be required for sister chromatid adhesion. Alternatively spliced transcript variants that encode different isoforms have been described.
