Genes affected

THOC5 (HGNC:19074): (THO complex subunit 5) Predicted to enable mRNA binding activity. Involved in several processes, including monocyte differentiation; negative regulation of DNA damage checkpoint; and viral mRNA export from host cell nucleus. Located in nucleoplasm. Part of THO complex part of transcription export complex. Colocalizes with chromosome, telomeric region. Implicated in breast carcinoma. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.946G>C (p.A316P) alteration is located in exon 11 (coding exon 9) of the THOC5 gene. This alteration results from a G to C substitution at nucleotide position 946, causing the alanine (A) at amino acid position 316 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
