Genes affected

DSTN (HGNC:15750): (destrin, actin depolymerizing factor) The product of this gene belongs to the actin-binding proteins ADF family. This family of proteins is responsible for enhancing the turnover rate of actin in vivo. This gene encodes the actin depolymerizing protein that severs actin filaments (F-actin) and binds to actin monomers (G-actin). Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.300G>A (p.M100I) alteration is located in exon 2 (coding exon 2) of the DSTN gene. This alteration results from a G to A substitution at nucleotide position 300, causing the methionine (M) at amino acid position 100 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
