Genes affected

MFN1 (HGNC:18262): (mitofusin 1) The protein encoded by this gene is a mediator of mitochondrial fusion. This protein and mitofusin 2 are homologs of the Drosophila protein fuzzy onion (Fzo). They are mitochondrial membrane proteins that interact with each other to facilitate mitochondrial targeting. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.012904614).

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00184 (2573/1397278) while in subpopulation MID AF= 0.0282 (152/5386). AF 95% confidence interval is 0.0246. There are 15 homozygotes in gnomad4_exome. There are 1330 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
