Genes affected
ELOA2 (HGNC:30771): (elongin A2) This gene encodes the transcriptionally active subunit of the SIII (or elongin) transcription elongation factor complex, which also includes two regulatory subunits, elongins B and C. This complex acts to increase the rate of RNA chain elongation by RNA polymerase II by suppressing transient pausing of the polymerase at many sites along the DNA template. Whereas a related protein with similar function, elongin A, is ubiquitously expressed, the encoded protein is specifically expressed in the testis, suggesting it may have a role in spermatogenesis.

KATNAL2 (HGNC:25387): (katanin catalytic subunit A1 like 2) Predicted to enable microtubule-severing ATPase activity. Predicted to be involved in cytoplasmic microtubule organization. Located in cytoplasm; microtubule; and spindle pole. [provided by Alliance of Genome Resources, Apr 2022]
