Genes affected

HEY1 (HGNC:4880): (hes related family bHLH transcription factor with YRPW motif 1) This gene encodes a nuclear protein belonging to the hairy and enhancer of split-related (HESR) family of basic helix-loop-helix (bHLH)-type transcriptional repressors. Expression of this gene is induced by the Notch and c-Jun signal transduction pathways. Two similar and redundant genes in mouse are required for embryonic cardiovascular development, and are also implicated in neurogenesis and somitogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

The c.349G>T (p.A117S) alteration is located in exon 5 (coding exon 5) of the HEY1 gene. This alteration results from a G to T substitution at nucleotide position 349, causing the alanine (A) at amino acid position 117 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
