Genes affected

BHLHE22 (HGNC:11963): (basic helix-loop-helix family member e22) This gene encodes a protein that belongs to the basic helix-loop-helix (bHLH) family of transcription factors that regulate cell fate determination, proliferation, and differentiation. A similar protein in mouse is required for the development of the dorsal cochlear nuclei, and is thought to play a role in in the differentiation of neurons involved in sensory input. The mouse protein also functions in retinogenesis. [provided by RefSeq, Oct 2016]

Collection Method: clinical testing

The c.196G>C (p.E66Q) alteration is located in exon 1 (coding exon 1) of the BHLHE22 gene. This alteration results from a G to C substitution at nucleotide position 196, causing the glutamic acid (E) at amino acid position 66 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
