Genes affected

COTL1 (HGNC:18304): (coactosin like F-actin binding protein 1) This gene encodes one of the numerous actin-binding proteins which regulate the actin cytoskeleton. This protein binds F-actin, and also interacts with 5-lipoxygenase, which is the first committed enzyme in leukotriene biosynthesis. Although this gene has been reported to map to chromosome 17 in the Smith-Magenis syndrome region, the best alignments for this gene are to chromosome 16. The Smith-Magenis syndrome region is the site of two related pseudogenes. [provided by RefSeq, Jul 2008]

The c.262G>A (p.G88R) alteration is located in exon 3 (coding exon 3) of the COTL1 gene. This alteration results from a G to A substitution at nucleotide position 262, causing the glycine (G) at amino acid position 88 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
