Genes affected

CYCS (HGNC:19986): (cytochrome c, somatic) This gene encodes a small heme protein that functions as a central component of the electron transport chain in mitochondria. The encoded protein associates with the inner membrane of the mitochondrion where it accepts electrons from cytochrome b and transfers them to the cytochrome oxidase complex. This protein is also involved in initiation of apoptosis. Mutations in this gene are associated with autosomal dominant nonsyndromic thrombocytopenia. Numerous processed pseudogenes of this gene are found throughout the human genome.[provided by RefSeq, Jul 2010]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 7-25122022-C-CA is Benign according to our data. Variant chr7-25122022-C-CA is described in ClinVar as [Likely_benign]. Clinvar id is 359924.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.409 is higher than 0.05.
