[Partial "de novo" trisomy 10q (author's transl)]

Area of Science:

• Genetics
• Human Chromosome Abnormalities
• Clinical Genetics

Background:

• Trisomy refers to the presence of an extra chromosome or part of a chromosome.
• Partial 10q trisomy involves having an extra copy of a segment of the long arm of chromosome 10.
• De novo translocations occur as new events in an individual, not inherited from parents.

Observation:

• A case of partial 10q trisomy is presented, resulting from a de novo translocation t(10;22).
• The specific chromosomal segment involved was identified as 10q24 to 10q26.
• This genetic alteration was observed in a single patient.

Findings:

• The study identifies a distinct clinical syndrome associated with trisomy for the 10q24-10q26 bands.
• Comparison with existing literature on partial 10q trisomy cases supports the delineation of this specific syndrome.
• The findings highlight the critical role of the 10q24-10q26 region in the observed phenotype.

Implications:

• This research contributes to a better understanding of genotype-phenotype correlations in chromosomal abnormalities.
• The identified syndrome provides a new diagnostic entity for clinicians evaluating patients with similar genetic findings.
• Further research may elucidate the specific genes within the 10q24-10q26 region responsible for the syndrome's features.
