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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.52G>A (p.V18I) alteration is located in exon 1 (coding exon 1) of the ASCL2 gene. This alteration results from a G to A substitution at nucleotide position 52, causing the valine (V) at amino acid position 18 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
