Genes affected
PTCD1 (HGNC:22198): (pentatricopeptide repeat domain 1) This gene encodes a mitochondrial protein that binds leucine tRNAs and other mitochondrial RNAs and plays a role in the regulation of translation. Increased expression of this gene results in decreased mitochondrial leucine tRNA levels. Naturally occurring read-through transcription exists between upstream ATP5J2 (ATP synthase, H+ transporting, mitochondrial Fo complex, subunit F2) and this gene. [provided by RefSeq, Aug 2015]
ATP5MF-PTCD1 (HGNC:38844): (ATP5MF-PTCD1 readthrough) This locus represents naturally occurring read-through transcription between the ATP5J2 (ATP synthase, H+ transporting, mitochondrial Fo complex, subunit F2) and PTCD1 (pentatricopeptide repeat domain 1) genes on chromosome 7. The read-through transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Nov 2010]

The c.1645G>C (p.G549R) alteration is located in exon 7 (coding exon 7) of the ATP5J2-PTCD1 gene. This alteration results from a G to C substitution at nucleotide position 1645, causing the glycine (G) at amino acid position 549 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
