Genes affected

MGARP (HGNC:29969): (mitochondria localized glutamic acid rich protein) Predicted to be involved in several processes, including axonal transport; cellular response to hormone stimulus; and protein targeting to mitochondrion. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

MGARP links:

NDUFC1 (HGNC:7705): (NADH:ubiquinone oxidoreductase subunit C1) The encoded protein is a subunit of the NADH:ubiquinone oxidoreductase (complex I), the first enzyme complex in the electron transport chain located in the inner mitochondrial membrane. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

Ambry Genetics

Feb 17, 2022

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
