Genes affected

RPP14 (HGNC:30327): (ribonuclease P/MRP subunit p14) This gene encodes a subunit of ribonuclease P and has 3' to 5' exoribonuclease activity. Transcripts for this gene are bicistronic and include a conserved downstream open reading frame for the hydroxyacyl-thioester dehydratase type 2 (HTD2) gene. [provided by RefSeq, May 2017]

HTD2 (HGNC:53111): (hydroxyacyl-thioester dehydratase type 2) This gene encodes a protein that localizes to the mitochondria and can function as a 3-hydroxyacyl thioester dehydratase. This gene is located just downstream of the gene for ribonuclease P/MRP subunit p14 (RPP14) in a genomic context that is conserved among animals. The upstream RPP14 gene is thought to be co-transcribed with this gene, and bicistronic transcripts may include open reading frames for both proteins. [provided by RefSeq, May 2017]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07353914).
