We report on maternal first cousins with bilateral microtia, micrognathia, cleft palate and hematologic findings of Diamond-Blackfan anemia (DBA). The similarity of findings shared between our cases and a female reported by Hasan and Inoue [1993] suggests that this is a distinctive syndrome, rather than a chance as...
What type of sequences do enhancers evolve from?
Studies have identified enhancers that were pivotal for morphological divergence and highlighted how novel genetic networks shaping form emerged from pre-existing ones.Most of the recently evolved enhancers arise from ancestral dna exaptation , rather than lineage-specific expansions of repeat elements.
The sequences of some gene regulatory elements diverge considerably, even between closely related species. A detailed analysis of the fast-evolving sparkling enhancer in Drosophila now identifies key compensatory mechanisms and 'grammar' elements that are critical for maintaining functional integrity. Author inf...
