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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 10-58388016-A-G is Benign according to our data. Variant chr10-58388016-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1317894.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0127 (1930/152300) while in subpopulation AMR AF= 0.0247 (377/15284). AF 95% confidence interval is 0.0226. There are 12 homozygotes in gnomad4. There are 913 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 12 AR gene
