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]

Ambry Genetics

Nov 13, 2023

The c.1280A>T (p.Y427F) alteration is located in exon 8 (coding exon 8) of the SESN1 gene. This alteration results from a A to T substitution at nucleotide position 1280, causing the tyrosine (Y) at amino acid position 427 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
