Genes affected

DNM3 (HGNC:29125): (dynamin 3) This gene encodes a member of a family of guanosine triphosphate (GTP)-binding proteins that associate with microtubules and are involved in vesicular transport. The encoded protein functions in the development of megakaryocytes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

The c.719A>G (p.K240R) alteration is located in exon 6 (coding exon 6) of the DNM3 gene. This alteration results from a A to G substitution at nucleotide position 719, causing the lysine (K) at amino acid position 240 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
