By reconstructing phylogenetic patterns and phylogeographical distribution from mitochondrial and Y haplogroups and genome-wide data, new evidence shows that the Pre-Austronesians may have originated in the coastal southeastern China (centered on Fujian) during the very early Neolithic Age (>10Kya) and lived on the marine subsistence in addition to hunting-gathering. They subsequently mixed with some ancient northern Chinese (from Shandong) and introduced mixed millets and rice cultivation, forming the Proto-Austronesian people ~7-10Kya. Later, Early Austronesians (~4-7Kya) evolved and migrated to Taiwan (~6Kya), and then spread to Island Southeast Asia (ISEA), Champa, southern Thailand, Madagascar, and Oceania via the Philippines (~4.1Kya). The second source is the Austroasiatic ancestors, who originated in southern China in the early Neolithic Age and migrated to the ISEA via the Mainland Southeast Asia and Malay Peninsula in the late Neolithic Age. They mixed with the core Austronesian speakers from Taiwan to become Austronesian speakers, and spread to Oceania. Linguistic and archaeological findings also support the Austronesian origins and genetic prehistory. Most recently, some Austronesians of ISEA have mixed with newcomers from South Asia. The Austronesian ancestors neither originated in the ISEA nor migrated directly from mainland China to the Philippines, also has nothing to do with the so-called \"two-layer\" hypothesis.

Most point mutations occur in tRNA genes. Here, we report a novel variant of the tRNAGlu gene associated with CPEO. A 45-year-old male presented with ptosis and external ophthalmoplegia; however, blood test results, including lactate levels and autoantibodies, were normal. CPEO was suspended, prompting additional myopathological examination, mtDNA sequencing analysis, long polymerase chain reaction (PCR) analysis, and single-fiber analysis to compare mutation loads between ragged-red fibers (RRFs) and non-RRFs. Histopathological examination revealed scattered COX-negative RRFs. No deletions were found in the mtDNA. MtDNA sequencing analysis revealed a novel variant, m.14677 T > C, in the tRNAGlu gene, with Sanger sequencing indicating 45% heteroplasmy in the muscle tissue. Single-fiber analysis showed a significantly higher mutation load of m.14677 T > C in RRFs (range: 25.3–92.8%; median: 88.1%; n = 6) compared with non-RRFs (range: 3.5–85.9%; median: 17.1%; n = 5) (P = 0.03). Based on the significantly higher mutation load in RRFs than in non-RRFs, pathological evidence of mitochondrial disease, and the mutation’s occurrence at an evolutionarily conserved site, we concluded that m.14677 T > C, a novel variant of the tRNAGlu gene, is the cause of CPEO.

These amphipathic molecules are integral constituents of cellular membranes, playing pivotal roles in modulating membrane protein functionality and receptor-mediated signaling. Among glycosphingolipids, gangliosides, defined by their inclusion of sialic acid residues, are abundantly enriched in the central nervous system. Notably, four predominant species, GM1, GD1a, GD1b, and GT1b, constitute the majority of gangliosides in the mammalian brain and are indispensable for neuronal development, synaptic architecture, and signal transduction. These gangliosides are critically involved in neurogenesis, differentiation, membrane stability, and the modulation of receptor function, ion channel activity, and immunological signaling within the nervous system. The biosynthesis of these gangliosides is orchestrated by key enzymes, including GM3 synthase (ST3GAL5) and GM2/GD2 synthase (B4GALNT1) catalyzing the formation of downstream intermediates. Pathogenic variants in ST3GAL5 result in GM3 synthase deficiency (GM3SD), an autosomal recessive disorder characterized by infantile-onset epileptic encephalopathy and profound developmental regression. In contrast, biallelic mutations in B4GALNT1 cause a complex form of hereditary spastic paraplegia (SPG26), marked by progressive spasticity and intellectual impairment.
