Genes affected

ASCL2 (HGNC:739): (achaete-scute family bHLH transcription factor 2) This gene is a member of the basic helix-loop-helix (BHLH) family of transcription factors. It activates transcription by binding to the E box (5'-CANNTG-3'). Dimerization with other BHLH proteins is required for efficient DNA binding. Involved in the determination of the neuronal precursors in the peripheral nervous system and the central nervous system. [provided by RefSeq, Jul 2008]

The c.149C>G (p.A50G) alteration is located in exon 1 (coding exon 1) of the ASCL2 gene. This alteration results from a C to G substitution at nucleotide position 149, causing the alanine (A) at amino acid position 50 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
