Genes affected

SHROOM3 (HGNC:30422): (shroom family member 3) This gene encodes a PDZ-domain-containing protein that belongs to a family of Shroom-related proteins. This protein may be involved in regulating cell shape in certain tissues. A similar protein in mice is required for proper neurulation. [provided by RefSeq, Jan 2011]

SHROOM3 Gene-Disease associations (from GenCC):

• neural tube defect

  Inheritance: AD Classification: STRONG Submitted by: G2P
• syndromic disease

  Inheritance: AR Classification: MODERATE Submitted by: PanelApp Australia

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
