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]

Collection Method: clinical testing

The c.180C>G (p.S60R) alteration is located in exon 2 (coding exon 1) of the ASCL3 gene. This alteration results from a C to G substitution at nucleotide position 180, causing the serine (S) at amino acid position 60 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
