Genes affected

TFAM (HGNC:11741): (transcription factor A, mitochondrial) This gene encodes a key mitochondrial transcription factor containing two high mobility group motifs. The encoded protein also functions in mitochondrial DNA replication and repair. Sequence polymorphisms in this gene are associated with Alzheimer's and Parkinson's diseases. There are pseudogenes for this gene on chromosomes 6, 7, and 11. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

Jun 30, 2022

The c.139G>A (p.A47T) alteration is located in exon 2 (coding exon 2) of the TFAM gene. This alteration results from a G to A substitution at nucleotide position 139, causing the alanine (A) at amino acid position 47 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
