Genes affected

CRY1 (HGNC:2384): (cryptochrome circadian regulator 1) This gene encodes a flavin adenine dinucleotide-binding protein that is a key component of the circadian core oscillator complex, which regulates the circadian clock. 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 have been associated with altered sleep patterns. The encoded protein is widely conserved across plants and animals. Loss of the related gene in mouse results in a shortened circadian cycle in complete darkness. [provided by RefSeq, Jan 2014]

The c.1313G>T (p.G438V) alteration is located in exon 9 (coding exon 9) of the CRY1 gene. This alteration results from a G to T substitution at nucleotide position 1313, causing the glycine (G) at amino acid position 438 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
