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]

The c.1711A>G (p.S571G) alteration is located in exon 17 (coding exon 16) of the DZANK1 gene. This alteration results from a A to G substitution at nucleotide position 1711, causing the serine (S) at amino acid position 571 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
