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.115G>T (p.A39S) alteration is located in exon 1 (coding exon 1) of the RAB40AL gene. This alteration results from a G to T substitution at nucleotide position 115, causing the alanine (A) at amino acid position 39 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
