The MYO6 c.3137+1G>A variant is predicted to disrupt the GT donor site and interfere with normal splicing. To our knowledge, this variant has not been reported in the literature. The disruption of this splice donor site may lead to an exon skipping and result in an in-frame deletion of ten amino acids, however no mRNA studies are available to evaluate the actual effect of this variant. This variant is reported in 0.017% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/6-76604978-G-A) and is interpreted as uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/1723638/). Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
