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.

The c.977A>G (p.N326S) alteration is located in exon 10 (coding exon 9) of the PAPD7 gene. This alteration results from a A to G substitution at nucleotide position 977, causing the asparagine (N) at amino acid position 326 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
