Partial trisomy 8q resulting from maternal translocation t(2;8)(q373;q23)

Area of Science:

• Genetics
• Clinical Medicine
• Developmental Biology

Background:

• Partial trisomy 8q, a rare chromosomal abnormality, involves the duplication of genetic material on the long arm of chromosome 8.
• Congenital malformations encompass a wide range of physical defects present at birth, affecting various body parts and functions.

Observation:

• A case report detailing a patient with multiple congenital malformations.
• The patient's karyotype revealed a partial trisomy of chromosome 8q.

Findings:

• Karyotype-phenotype correlation analysis was performed.
• The specific pattern of malformations observed in this patient, linked to the partial 8q trisomy, supports a distinct syndromic classification.

Implications:

• This case contributes to the understanding of the genetic basis of congenital malformations.
• Identifying partial trisomy 8q as a distinct syndrome could improve diagnostic accuracy and genetic counseling for affected families.
• Further research into additional cases is warranted to solidify the nosological status of partial trisomy 8q syndrome.
