Genes affected

DDIAS (HGNC:26351): (DNA damage induced apoptosis suppressor) Involved in negative regulation of intrinsic apoptotic signaling pathway in response to DNA damage and regulation of DNA stability. Predicted to be active in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

DDIAS links:

PRCP (HGNC:9344): (prolylcarboxypeptidase) This gene encodes a member of the peptidase S28 family of serine exopeptidases. The encoded preproprotein is proteolytically processed to generate the mature lysosomal prolylcarboxypeptidase. This enzyme cleaves C-terminal amino acids linked to proline in peptides such as angiotension II, III and des-Arg9-bradykinin. The cleavage occurs at acidic pH, but the enzyme activity is retained with some substrates at neutral pH. This enzyme has been shown to be an activator of the cell matrix-associated prekallikrein. The importance of angiotension II, one of the substrates of this enzyme, in regulating blood pressure and electrolyte balance suggests that this gene may be related to essential hypertension. A pseudogene of this gene has been identified on chromosome 2. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Jan 2016]

Ambry Genetics

May 27, 2022

The c.661G>A (p.D221N) alteration is located in exon 6 (coding exon 4) of the DDIAS gene. This alteration results from a G to A substitution at nucleotide position 661, causing the aspartic acid (D) at amino acid position 221 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
