Genes affected

AK7 (HGNC:20091): (adenylate kinase 7) This gene encodes a member of the adenylate kinase family of enzymes. The encoded enzyme is a phosphotransferase that catalyzes the reversible phosphorylation of adenine nucleotides. This enzyme plays a role in energy homeostasis of the cell. Alternative splicing results in multiple transcript variants. Mutations in the mouse gene are associated with primary ciliary dyskinesia. [provided by RefSeq, Apr 2017]

This variant, c.165_170del, results in the deletion of 2 amino acid(s) of the AK7 protein (p.Glu55_Glu56del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs779453953, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with AK7-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
