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:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2022The c.379C>T (p.R127C) alteration is located in exon 1 (coding exon 1) of the RAB40AL gene. This alteration results from a C to T substitution at nucleotide position 379, causing the arginine (R) at amino acid position 127 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
