Genes affected

ZFHX2 (HGNC:20152): (zinc finger homeobox 2) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in regulation of sensory perception of pain. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ZFHX2 links:

ZFHX2-AS1 (HGNC:52658): (ZFHX2 antisense RNA 1)

ZFHX2-AS1 links:

THTPA (HGNC:18987): (thiamine triphosphatase) This gene encodes an enzyme which catalyzes the biosynthesis of thiamine disphophate (vitamin B1) by hydrolysis of thiamine triphosphate. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2011]
