Genes affected

RNASE8 (HGNC:19277): (ribonuclease A family member 8) The protein encoded by this gene belongs to the pancreatic ribonuclease family, a subset of the ribonuclease A superfamily. The protein is expressed prominently in the placenta and exhibits antimicrobial activity against pathogenic bacteria and fungi. [provided by RefSeq, Oct 2014]

RNASE8 links:

NDRG2 (HGNC:14460): (NDRG family member 2) This gene is a member of the N-myc downregulated gene family which belongs to the alpha/beta hydrolase superfamily. The protein encoded by this gene is a cytoplasmic protein that may play a role in neurite outgrowth. This gene may be involved in glioblastoma carcinogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2017]

Ambry Genetics

May 13, 2024

The c.44T>G (p.L15R) alteration is located in exon 1 (coding exon 1) of the RNASE8 gene. This alteration results from a T to G substitution at nucleotide position 44, causing the leucine (L) at amino acid position 15 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
