Genes affected

THOC6 (HGNC:28369): (THO complex subunit 6) This gene encodes a subunit of the multi-protein THO complex, which is involved in coordination between transcription and mRNA processing. The THO complex is a component of the TREX (transcription/export) complex, which is involved in transcription and export of mRNAs. A missense mutation in this gene is associated with a neurodevelopmental disorder called Beaulieu-Boycott-Innes syndrome. [provided by RefSeq, Dec 2016]

The c.46G>A (p.V16M) alteration is located in exon 2 (coding exon 2) of the THOC6 gene. This alteration results from a G to A substitution at nucleotide position 46, causing the valine (V) at amino acid position 16 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
