Genes affected

RAB40AL (HGNC:25410): (RAB40A like) This gene encodes a member of the Rab40 subfamily of Rab small GTP-binding proteins that contains a C-terminal suppressors of cytokine signaling box. Disruptions in this gene are associated with Duchenne muscular dystrophy. [provided by RefSeq, Apr 2010]

The c.649G>A (p.A217T) alteration is located in exon 1 (coding exon 1) of the RAB40AL gene. This alteration results from a G to A substitution at nucleotide position 649, causing the alanine (A) at amino acid position 217 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
