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]

Submissions by phenotype

not specified Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 17, 2023The c.660C>G (p.S220R) alteration is located in exon 1 (coding exon 1) of the RAB40AL gene. This alteration results from a C to G substitution at nucleotide position 660, causing the serine (S) at amino acid position 220 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
