Genes affected

ZNF407 (HGNC:19904): (zinc finger protein 407) This gene encodes a zinc finger protein whose exact function is not known. It may be involved in transcriptional regulation. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.51).
• BP7: Synonymous conserved (PhyloP=-0.956 with no splicing effect.
