Genes affected

HEYL (HGNC:4882): (hes related family bHLH transcription factor with YRPW motif like) This gene encodes a member of the hairy and enhancer of split-related (HESR) family of basic helix-loop-helix (bHLH)-type transcription factors. The sequence of the encoded protein contains a conserved bHLH and orange domain, but its YRPW motif has diverged from other HESR family members. It is thought to be an effector of Notch signaling and a regulator of cell fate decisions. Alternatively spliced transcript variants have been found, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.531G>T (p.W177C) alteration is located in exon 5 (coding exon 5) of the HEYL gene. This alteration results from a G to T substitution at nucleotide position 531, causing the tryptophan (W) at amino acid position 177 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
