Genes affected

DTX1 (HGNC:3060): (deltex E3 ubiquitin ligase 1) Studies in Drosophila have identified this gene as encoding a positive regulator of the Notch-signaling pathway. The human gene encodes a protein of unknown function; however, it may play a role in basic helix-loop-helix transcription factor activity. [provided by RefSeq, Jul 2008]

The c.460A>T (p.N154Y) alteration is located in exon 2 (coding exon 2) of the DTX1 gene. This alteration results from a A to T substitution at nucleotide position 460, causing the asparagine (N) at amino acid position 154 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
