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]

The c.3329G>A (p.R1110Q) alteration is located in exon 15 (coding exon 15) of the FMN1 gene. This alteration results from a G to A substitution at nucleotide position 3329, causing the arginine (R) at amino acid position 1110 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
