Genes affected

DDI1 (HGNC:18961): (DNA damage inducible 1 homolog 1) Predicted to enable aspartic-type endopeptidase activity. Involved in several processes, including cellular response to hydroxyurea; proteasomal protein catabolic process; and regulation of DNA stability. [provided by Alliance of Genome Resources, Apr 2022]

DDI1 links:

PDGFD (HGNC:30620): (platelet derived growth factor D) The protein encoded by this gene is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a core motif of eight cysteines, seven of which are found in this factor. This gene product only forms homodimers and, therefore, does not dimerize with the other three family members. It differs from alpha and beta members of this family in having an unusual N-terminal domain, the CUB domain. Two splice variants have been identified for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Mar 19, 2024

The c.245C>T (p.P82L) alteration is located in exon 1 (coding exon 1) of the DDI1 gene. This alteration results from a C to T substitution at nucleotide position 245, causing the proline (P) at amino acid position 82 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
