Genes affected

ADCK2 (HGNC:19039): (aarF domain containing kinase 2) Predicted to enable ATP binding activity and protein serine/threonine kinase activity. Predicted to be involved in protein phosphorylation. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

ADCK2 links:

NDUFB2 (HGNC:7697): (NADH:ubiquinone oxidoreductase subunit B2) The protein encoded by this gene is a subunit of the multisubunit NADH:ubiquinone oxidoreductase (complex I). Mammalian complex I is composed of 45 different subunits. This protein has NADH dehydrogenase activity and oxidoreductase activity. It plays a important role in transfering electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone. Hydropathy analysis revealed that this subunit and 4 other subunits have an overall hydrophilic pattern, even though they are found within the hydrophobic protein (HP) fraction of complex I.

Collection Method: clinical testing

The c.1709C>G (p.S570C) alteration is located in exon 7 (coding exon 7) of the ADCK2 gene. This alteration results from a C to G substitution at nucleotide position 1709, causing the serine (S) at amino acid position 570 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
