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]

PTCD1 links:

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.1933G>A (p.A645T) alteration is located in exon 8 (coding exon 8) of the ATP5J2-PTCD1 gene. This alteration results from a G to A substitution at nucleotide position 1933, causing the alanine (A) at amino acid position 645 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
