Genes affected

PRAP1 (HGNC:23304): (proline rich acidic protein 1) Predicted to enable triglyceride binding activity. Involved in DNA damage response, signal transduction by p53 class mediator resulting in cell cycle arrest; deactivation of mitotic spindle assembly checkpoint; and negative regulation of apoptotic process. Predicted to be located in endoplasmic reticulum and extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

PRAP1 links:

ZNF511-PRAP1 (HGNC:38088): (ZNF511-PRAP1 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring ZNF511 (zinc finger protein 511) and PRAP1 (proline-rich acidic protein 1) genes on chromosome 10. The putative readthrough transcript may encode a fusion protein that shares sequence identity with each individual gene product and may be involved in the regulation of gene promoters, particularly those found on transfected plasmids.

Collection Method: clinical testing

The c.158C>G (p.P53R) alteration is located in exon 4 (coding exon 4) of the PRAP1 gene. This alteration results from a C to G substitution at nucleotide position 158, causing the proline (P) at amino acid position 53 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
