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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0371 (5646/152332) while in subpopulation NFE AF= 0.0473 (3217/68032). AF 95% confidence interval is 0.0459. There are 114 homozygotes in gnomad4. There are 2656 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd at 5641 AD gene.
