Imprinting syndrome
Witryna17 lut 2024 · Imprinting is implemented by an epigenetic process, most often initiated by methylation of cytosines in a certain DNA-stretch. In case of exclusive presence of paternal or maternal imprinted allele (s) a corresponding syndrome may appear [ 1, 3 ]. Witryna12 maj 2024 · Imprinting disorders are rare events and our results are based on few ART children with imprinting disorders. The aetiology is complex and only partly clarified, and the clinical diagnoses are challenged by a broad phenotypic spectrum. WIDER IMPLICATIONS OF THE FINDINGS:
