Genes affected

ASCL3 (HGNC:740): (achaete-scute family bHLH transcription factor 3) Basic helix-loop-helix transcription factors, such as ASCL3, are essential for the determination of cell fate and the development and differentiation of numerous tissues (Jonsson et al., 2004 [PubMed 15475265]).[supplied by OMIM, Mar 2008]
