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]

The c.49T>G (p.S17A) alteration is located in exon 2 (coding exon 1) of the RPP14 gene. This alteration results from a T to G substitution at nucleotide position 49, causing the serine (S) at amino acid position 17 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
