Genes affected
DZANK1 (HGNC:15858): (double zinc ribbon and ankyrin repeat domains 1) This gene contains two ankyrin repeat-encoding regions. Ankyrin repeats are tandemly repeated modules of about 33 amino acids described as L-shaped structures consisting of a beta-hairpin and two alpha-helices. Ankyrin repeats occur in a large number of functionally diverse proteins, mainly from eukaryotes, and are known to function as protein-protein interaction domains. [provided by RefSeq, Dec 2018]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2023The c.1645G>A (p.D549N) alteration is located in exon 16 (coding exon 15) of the DZANK1 gene. This alteration results from a G to A substitution at nucleotide position 1645, causing the aspartic acid (D) at amino acid position 549 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
