Genes affected

VANGL1 (HGNC:15512): (VANGL planar cell polarity protein 1) This gene encodes a member of the tretraspanin family. The encoded protein may be involved in mediating intestinal trefoil factor induced wound healing in the intestinal mucosa. Mutations in this gene are associated with neural tube defects. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2010]

VANGL1 Gene-Disease associations (from GenCC):

• neural tube defects, susceptibility to

  Inheritance: AD Classification: LIMITED Submitted by: G2P

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.143 is higher than 0.05.
