Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_145202.5(PRAP1):​c.208C>A​(p.Leu70Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,460,864 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L70V) has been classified as Uncertain significance.

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]
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.
