Genes affected

NFIL3 (HGNC:7787): (nuclear factor, interleukin 3 regulated) The protein encoded by this gene is a transcriptional regulator that binds as a homodimer to activating transcription factor (ATF) sites in many cellular and viral promoters. The encoded protein represses PER1 and PER2 expression and therefore plays a role in the regulation of circadian rhythm. Three transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Feb 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.15623987).

The c.92C>T (p.A31V) alteration is located in exon 2 (coding exon 1) of the NFIL3 gene. This alteration results from a C to T substitution at nucleotide position 92, causing the alanine (A) at amino acid position 31 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
