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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 30, 2023 | The c.349C>T (p.R117C) alteration is located in exon 2 (coding exon 1) of the ASCL3 gene. This alteration results from a C to T substitution at nucleotide position 349, causing the arginine (R) at amino acid position 117 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
