Dimethylacetals pattern [Interpretation] in Red Blood Cells Narrative

DMA pattern RBC-Imp

Definition

  • The pattern of dimethylacetals (DMAs), including DMA 16:0 (1,1-Dimethoxyhexadecane), DMA 18:0 (1,1-Dimethoxyoctadecane), and DMA 18:1 (1,1-dimethoxy-(9Z)octadecene), in red blood cells is used to diagnosis plasmalogen synthesis disorders, including retinitis pigmentosa (RP), rhizomelic chondrodysplasia punctata and Zellweger disease spectrum. Schaefer et. al. (1995) found that dominant, recessive, and isolated forms of RP have higher ratios of DMA 16:0/C16:0, DMA 18:0/C18:0 and DMA 18:1n9/C18:1n9 compared to controls. For X-linked RP, only the DMA 18:1n9/C18:1n9 ratio was significantly higher than in controls.[PMID: 7595066] The ratio of DMA 18:0/C18:0 is reportedly lower in patients with In Zellweger syndrome.[PMID: 3760714]
