Genes affected

PER2 (HGNC:8846): (period circadian regulator 2) This gene is a member of the Period family of genes and is expressed in a circadian pattern in the suprachiasmatic nucleus, the primary circadian pacemaker in the mammalian brain. Genes in this family encode components of the circadian rhythms of locomotor activity, metabolism, and behavior. This gene is upregulated by CLOCK/ARNTL heterodimers but then represses this upregulation in a feedback loop using PER/CRY heterodimers to interact with CLOCK/ARNTL. Polymorphisms in this gene may increase the risk of getting certain cancers and have been linked to sleep disorders. [provided by RefSeq, Jan 2014]

The c.3002A>G (p.E1001G) alteration is located in exon 19 (coding exon 18) of the PER2 gene. This alteration results from a A to G substitution at nucleotide position 3002, causing the glutamic acid (E) at amino acid position 1001 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
