Genes affected

VIL1 (HGNC:12690): (villin 1) This gene encodes a member of a family of calcium-regulated actin-binding proteins. This protein represents a dominant part of the brush border cytoskeleton which functions in the capping, severing, and bundling of actin filaments. Two mRNAs of 2.7 kb and 3.5 kb have been observed; they result from utilization of alternate poly-adenylation signals present in the terminal exon. [provided by RefSeq, Jul 2008]

The c.275G>A (p.R92Q) alteration is located in exon 4 (coding exon 3) of the VIL1 gene. This alteration results from a G to A substitution at nucleotide position 275, causing the arginine (R) at amino acid position 92 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
