Chromosome Studies for Congenital Disorders
Diagnostic testing for Fanconi anemia.
Diagnostic testing for Bloom syndrome.
This test is useful for detecting increased spontaneous chromosomal breakage in patients with ataxia telangiectasia (AT) or Louis-Bar syndrome, and Nijmegen breakage syndrome (NBS) (chromosomal breakage syndromes).

FISH (Fluorescence In Situ Hybridization) Studies for Congenital Disorders
This test is only appropriate to better define the extent of a 15q11.2 deletion originally detected by #81153 - Prader-Willi/Angelman Syndrome, Molecular Analysis.
This test is only appropriate for detection of low levels of sex chromosome mosaicism when a karyotype of 45,X has been observed.
This test is appropriate to aid in the detection of the SRY gene in XX males and XY females.  Must be ordered in conjunction with conventional chromosome studies (8696).
This test is only appropriate as a supplement to conventional chromosome studies when an alternative tissue needs to be studied to detect sex chromosome aneuploidy.

Sex Chromosome Abnormalities
This test is only appropriate to detect low levels of sex chromosome mosaicism when a karyotype of 45,X has been observed.
This test is appropriate to aid in the detection of the SRY gene in XX males and XY females.  Must be ordered in conjunction with conventional chromosome studies (8696).
This test is only appropriate as a supplement to conventional chromosome studies when an alternative tissue needs to be studied to detect sex chromosome aneuploidy.
This test is only appropriate to characterize X-derived structurally abnormal chromosomes.
