Genes affected

FMN1 (HGNC:3768): (formin 1) This gene belongs to the formin homology family and encodes a protein that has a role in the formation of adherens junction and the polymerization of linear actin cables. The homologous gene in mouse is associated with limb deformity. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2015]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.619 is higher than 0.05.
