    This study details a rare interstitial deletion on chromosome 2, specifically del(2)(q31-q33), in an infant with severe developmental delays and congenital anomalies. Comparing this case with others helps understand this genetic condition.

    Area of Science:

    • Genetics
    • Developmental Biology
    • Clinical Medicine

    Background:

    • Genetic disorders can cause significant developmental challenges and congenital anomalies.
    • Chromosome 2 deletions are rare and can lead to complex phenotypes.
    • Understanding specific chromosomal abnormalities is crucial for diagnosis and management.

    Observation:

    • An 8-month-old female presented with severe growth and developmental retardation.
    • The infant exhibited multiple congenital anomalies.
    • Cytogenetic analysis revealed an interstitial deletion on chromosome 2, specifically del(2)(q31-q33).

    Findings:

    • The identified deletion encompasses specific genetic markers on chromosome 2q.
    • Comparison with four previously reported patients with partial del(2q) reveals overlapping and distinct clinical features.

    Related Experiment Videos

  • This case contributes to the understanding of the phenotypic spectrum associated with 2q deletions.

    • Implications:

    • This research aids in characterizing the clinical manifestations of del(2)(q31-q33).
    • Improved understanding can lead to better genetic counseling and diagnostic approaches for similar cases.
    • Further research into the specific genes within the deleted region may elucidate their roles in development.
