New microdeletion and microduplication syndromes: A comprehensive review

Area of Science:

• Genetics
• Developmental Biology
• Clinical Medicine

Background:

• Emerging microdeletion and microduplication syndromes are linked to multisystem disorders.
• These genetic conditions often present with intellectual disability (ID), multiple congenital anomalies (MCA), and autistic spectrum disorders (ASD).

Purpose of the Study:

• To review newly identified microdeletion and microduplication syndromes.
• To summarize key characteristics and involved chromosomal regions of these emergent genetic disorders.
• To provide a guide for clinicians and geneticists.

Main Methods:

• Literature review of recently described microdeletion and microduplication syndromes.
• Classification of syndromes based on genomic region.
• Categorization by associated findings: ID, MCA, ASD, or other phenotypes.

Main Results:

• Identification and characterization of several novel microdeletion and microduplication syndromes.
• Mapping of these syndromes to specific chromosomal regions.
• Correlation of genetic regions with specific phenotypic outcomes including ID, MCA, and ASD.

Conclusions:

• Emerging microdeletion and microduplication syndromes represent a significant group of genetic disorders.
• Understanding their genetic basis and phenotypic spectrum is crucial for diagnosis and management.
• This review serves as a practical guide for healthcare professionals.
