The c.889_891delGAG variant has been reported in an individual with very long chain acyl-CoA dehydrogenase (VLCAD) deficiency who was heterozygous for another variant in the ACADVL gene (Brown et al., 2014). The c.889_891delGAG variant causes the loss of a single Glutamic Acid residue at amino acid position 297, denoted p.Glu297del. The Glu297 amino acid is a highly conserved residue that is located in a functional region of the ACADVL protein. Other deletions of single amino acids (p.Glu130del, p.Lys299del) have been reported in association with VLCAD deficiency (Souri et al., 1996). Therefore we interpret c.889_891delGAG to be a likely pathogenic variant.
