Genes affected

CRY2 (HGNC:2385): (cryptochrome circadian regulator 2) 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2014]

The c.109G>C (p.A37P) alteration is located in exon 1 (coding exon 1) of the CRY2 gene. This alteration results from a G to C substitution at nucleotide position 109, causing the alanine (A) at amino acid position 37 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
