Extended Genetic Testing

Over the years, we have expanded our genetic testing of sperm donors as genetic knowledge and technology have advanced. As a result, not all donors have been tested for the same conditions or with the same methods. All donors have undergone genetic testing for Cystic Fibrosis, Spinal Muscular Atrophy and Karyotyping. However, many donors have had more extensive testing performed.  For a full list of our donors who have had Extended Genetic Testing performed please go to click HERE

Even if a donor has been evaluated for carrier status of the listed conditions below, a negative result reduces, but does not eliminate, the likelihood of the donor being a carrier. If you are a known carrier of a genetic condition please contact us, and we will provide a copy of the donor’s test reports to your physician and/or genetic counselor.

Seattle Sperm Bank currently tests all* donors for carrier status of the following conditions:

Bloom syndrome
Canavan disease
cystic fibrosis
familial dysautonomia
Fanconi anemia type C
Gaucher disease
glycogen storage disease type Ia
Hb beta chain-related hemoglobinopathy (including beta thalassemia and sickle cell disease)
hexosaminidase A deficiency (including Tay-Sachs disease)
Joubert syndrome 2
lipoamide dehydrogenase deficiency
maple syrup urine disease type 1B
mucolipidosis IV
NEB-related nemaline myopathy
Niemann-Pick disease, SMPD1-associated
spinal muscular atrophy
Usher syndrome type 1F
Usher syndrome type 3

*Donors who joined Seattle Sperm Bank’s program prior to September 2015 may not have been tested for all of the conditions listed above. All donors, regardless of when they entered our program have been screened for Karyotyping, Cystic Fibrosis and Spinal Muscular Atrophy.
