Our two new unrelated cases of Oliver McFarlane Syndrome demonstrate early ophthalmological and systemic findings of this rare syndrome and the progressive nature of the retinopathy with a long follow-up. PNPLA6-related disorders are a phenotypically highly heterogenous group where alterations in the phosphatidylcholine metabolism can lead to manifestations in different tissues with no clear genotype-phenotype correlation.
