The L84F variant has been reported previously in trans with K329E in an individual with a severe medium chain acyl-CoA dehydrogenase (MCAD) deficiency phenotype (Smith et al., 2010). This variant has also been observed in two individuals with positive newborn screening and biochemical testing suggestive of MCAD deficiency who were also heterozygous for another variant in ACADM (Waddell et al., 2006; Touw et al. 2012). The L84F variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The L84F variant occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. In summary, we interpret L84F to be a pathogenic variant.
