Genes affected

EXPH5 (HGNC:30578): (exophilin 5) The protein encoded by this gene is a member of the synaptotagmin-like protein (Slp) family lacking a C2 domain. It contains an N-terminal synaptotagmin-like homology domain (SHD), and is a ras-related protein Rab-27B effector protein. This protein is thought to be involved in exosome secretion and intracellular vesicle trafficking. Reduced expression of this gene results in keratin filament defects. Mutations in this gene have been associated with some cases of epidermolysis bullosa, an inherited skin fragility disorder. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2015]

The c.5681A>G (p.Q1894R) alteration is located in exon 6 (coding exon 6) of the EXPH5 gene. This alteration results from a A to G substitution at nucleotide position 5681, causing the glutamine (Q) at amino acid position 1894 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
