Genes affected

AMER1 (HGNC:26837): (APC membrane recruitment protein 1) The protein encoded by this gene upregulates trancriptional activation by the Wilms tumor protein and interacts with many other proteins, including CTNNB1, APC, AXIN1, and AXIN2. Defects in this gene are a cause of osteopathia striata with cranial sclerosis (OSCS). [provided by RefSeq, May 2010]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.
