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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.927
