Genes affected

SESN1 (HGNC:21595): (sestrin 1) This gene encodes a member of the sestrin family. Sestrins are induced by the p53 tumor suppressor protein and play a role in the cellular response to DNA damage and oxidative stress. The encoded protein mediates p53 inhibition of cell growth by activating AMP-activated protein kinase, which results in the inhibition of the mammalian target of rapamycin protein. The encoded protein also plays a critical role in antioxidant defense by regenerating overoxidized peroxiredoxins, and the expression of this gene is a potential marker for exposure to radiation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

ARMC2 (HGNC:23045): (armadillo repeat containing 2) Involved in sperm axoneme assembly. Implicated in spermatogenic failure 38. [provided by Alliance of Genome Resources, Apr 2022]

ARMC2 Gene-Disease associations (from GenCC):

• spermatogenic failure 38

  Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: ClinGen, Labcorp Genetics (formerly Invitae)
