Genes affected

KRR1 (HGNC:5176): (KRR1 small subunit processome component homolog) Enables RNA binding activity. Predicted to be involved in rRNA processing. Located in chromosome; intercellular bridge; and nuclear lumen. [provided by Alliance of Genome Resources, Apr 2022]

KRR1 links:

GLIPR1 (HGNC:17001): (GLI pathogenesis related 1) This gene encodes a protein with similarity to both the pathogenesis-related protein (PR) superfamily and the cysteine-rich secretory protein (CRISP) family. Increased expression of this gene is associated with myelomocytic differentiation in macrophage and decreased expression of this gene through gene methylation is associated with prostate cancer. The protein has proapoptotic activities in prostate and bladder cancer cells. This gene is a member of a cluster on chromosome 12 containing two other similar genes. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 28, 2024

The c.887G>A (p.R296Q) alteration is located in exon 8 (coding exon 8) of the KRR1 gene. This alteration results from a G to A substitution at nucleotide position 887, causing the arginine (R) at amino acid position 296 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
