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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.2081A>G (p.N694S) alteration is located in exon 9 (coding exon 9) of the ATP5J2-PTCD1 gene. This alteration results from a A to G substitution at nucleotide position 2081, causing the asparagine (N) at amino acid position 694 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
