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]

Ambry Genetics

Sep 12, 2024

The c.74T>C (p.V25A) alteration is located in exon 1 (coding exon 1) of the RAB40AL gene. This alteration results from a T to C substitution at nucleotide position 74, causing the valine (V) at amino acid position 25 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
