Abstract:

Objective

To investigate the relationship between clinical manifestations and genetic factors in a child with short stature, low sex hormone level and abnormal reproductive system development.

Methods

G-banded karyotyping and chromosomal microarray analysis (CMA) were performed on the child.

Results

The karyotype analysis showed that the patient had 46, X, +mar[52]/45, X[8]. CMA showed that there were 35.0 Mb and 72.1 Mb deletions (copy number 1) at Xp22.33p21.1 and Xq21.1q28, respectively, and about 48.6 Mb chimeric deletions (copy number 1.5) at xp21.1q21.1.

Conclusions

The clinical symptoms of this patient are related to the abnormal X chromosome, and the other symptoms are consistent with the manifestations of Turner syndrome. It is necessary to carry out cytogenetic examination for patients with second sexual syndrome and abnormal sexual organ development.

Key words: chromosome karyotyping, chromosome microarray analysis, chimera, Turner syndrome
