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: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.441 is higher than 0.05.
