Genes affected

FASTKD2 (HGNC:29160): (FAST kinase domains 2) This gene encodes a protein that is localized in the mitochondrial inner compartment and that may play a role in mitochondrial apoptosis. Nonsense mutations have been reported to result in cytochrome c oxidase deficiency. [provided by RefSeq, Oct 2008]

Uncertain significance, criteria provided, single submitter	clinical testing	Center for Pediatric Genomic Medicine, Children's Mercy Hospital and Clinics	May 01, 2017	- -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Feb 10, 2015	p.Asn575Asp (AAT>GAT): c.1723 A>G in exon 9 of the FASTKD2 gene (NM_014929.3). The N575D variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The N575D variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is moderately conserved across species. In silico analysis predicts this variant likely does not alter the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in MITONUC-MITOP panel(s). -
