Interpreting the Results of Your Karyotyping Test

Parameter/AnalyteNormal Finding (Example)Interpretation of Abnormal Finding (with ISCN examples)
Total Chromosome Count46More than 46 (e.g., 47 chromosomes) indicates aneuploidy such as trisomy. Example: 47,XX,+21 (female with an extra chromosome 21 = Down syndrome). Less than 46 (e.g., 45 chromosomes) indicates monosomy. Example: 45,X (Turner syndrome).
Sex ChromosomesXX (Female), XY (Male)Variations include: - 45,X (Turner Syndrome, monosomy X) - 47,XXY (Klinefelter Syndrome, extra X in males) - 47,XYY (Jacobs Syndrome) - 47,XXX (Triple X Syndrome) — all indicate sex chromosome aneuploidies.
Autosomal Chromosomes22 pairs, structurally normal (homologous pairs match)Numerical abnormalities: - Trisomy 13: 47,XX,+13 - Trisomy 18: 47,XY,+18 Structural abnormalities described by ISCN: - Deletion: del(5p) (deletion on short arm of chromosome 5) - Duplication, inversion, translocation - Translocation example: t(9;22)(q34;q11.2) (Philadelphia chromosome in CML)
Structural IntegrityNo visible deletions, duplications, translocationsPresence of structural abnormalities is indicated by specific notations, e.g.: - del(5p) deletion - inv(9)(p11q12) inversion on chromosome 9 - t(1;3)(p36;q21) translocation between chromosomes 1 and 3. These changes can affect gene function and clinical phenotype.
