Genes affected

DIXDC1 (HGNC:23695): (DIX domain containing 1) The protein encoded by this gene is a positive regulator of the Wnt signaling pathway. The encoded protein is found associated with gamma tubulin at the centrosome. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jun 2013]

Ambry Genetics

Dec 22, 2023

The c.802C>T (p.R268W) alteration is located in exon 7 (coding exon 7) of the DIXDC1 gene. This alteration results from a C to T substitution at nucleotide position 802, causing the arginine (R) at amino acid position 268 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
