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]

Ambry Genetics

Dec 21, 2022

The c.32C>G (p.P11R) alteration is located in exon 1 (coding exon 1) of the BHLHE40 gene. This alteration results from a C to G substitution at nucleotide position 32, causing the proline (P) at amino acid position 11 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
