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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.1619C>T (p.T540M) alteration is located in exon 7 (coding exon 7) of the ATP5J2-PTCD1 gene. This alteration results from a C to T substitution at nucleotide position 1619, causing the threonine (T) at amino acid position 540 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
