Notes
rs113994098, also known as c.2542G>A, p.Gly848Ser and G848S, represents a mutation in the POLG gene on chromosome 15. Inherited in a recessive manner, the uncommon rs113994098(A) allele is associated with a variety of syndromes involving ataxias, including mitochondrial DNA depletion syndrome type 4A (Alpers syndrome) and sensory ataxic neuropathy, dysarthria, and ophthalmoparesis (SANDO). 23andMe name: i5006724
