Genes affected

ZMYND8 (HGNC:9397): (zinc finger MYND-type containing 8) The protein encoded by this gene is a receptor for activated C-kinase (RACK) protein. The encoded protein has been shown to bind in vitro to activated protein kinase C beta I. In addition, this protein is a cutaneous T-cell lymphoma-associated antigen. Finally, the protein contains a bromodomain and two zinc fingers, and is thought to be a transcriptional regulator. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ZMYND8. . Gene score misZ 4.0385 (greater than the threshold 3.09). Trascript score misZ 5.0127 (greater than threshold 3.09). GenCC has associacion of gene with autism spectrum disorder.
