Genes affected

BHLHE40 (HGNC:1046): (basic helix-loop-helix family member e40) This gene encodes a basic helix-loop-helix protein expressed in various tissues. The encoded protein can interact with ARNTL or compete for E-box binding sites in the promoter of PER1 and repress CLOCK/ARNTL's transactivation of PER1. This gene is believed to be involved in the control of circadian rhythm and cell differentiation. [provided by RefSeq, Feb 2014]

The c.97A>G (p.M33V) alteration is located in exon 2 (coding exon 2) of the BHLHE40 gene. This alteration results from a A to G substitution at nucleotide position 97, causing the methionine (M) at amino acid position 33 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
