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. [provided by RefSeq, Jul 2008]
ELF2 (HGNC:3317): (E74 like ETS transcription factor 2) Enables DNA-binding transcription factor activity, RNA polymerase II-specific and sequence-specific double-stranded DNA binding activity. Involved in negative regulation of transcription, DNA-templated; positive regulation of transcription, DNA-templated; and regulation of transcription by RNA polymerase II. Located in cytosol and nuclear body. [provided by Alliance of Genome Resources, Apr 2022]

The c.847G>A (p.A283T) alteration is located in exon 3 (coding exon 3) of the NOCT gene. This alteration results from a G to A substitution at nucleotide position 847, causing the alanine (A) at amino acid position 283 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
