Genes affected

NOCT (HGNC:14254): (nocturnin) The protein encoded by this gene is highly similar to Nocturnin, a gene identified as a circadian clock regulated gene in Xenopus laevis. This protein and Nocturnin protein share similarity with the C-terminal domain of a yeast transcription factor, carbon catabolite repression 4 (CCR4). The mRNA abundance of a similar gene in mouse has been shown to exhibit circadian rhythmicity, which suggests a role for this protein in clock function or as a circadian clock effector.

Ambry Genetics

Jul 06, 2021

The c.32C>T (p.A11V) alteration is located in exon 1 (coding exon 1) of the NOCT gene. This alteration results from a C to T substitution at nucleotide position 32, causing the alanine (A) at amino acid position 11 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
