What Does NxGen MDx Screen For?
We screen for up to 120 genetic disorders that can affect your pregnancy, the health of your baby, and your family's future. You can learn more about our various screens — and which sets of screens (or "panels") align with where you are in your reproductive journey.
What Your Test Results Mean:
Test results indicate that you are a carrier of achromatopsia. Carriers are not expected to show symptoms of achromatopsia. You and your partner would both have to be carriers of achromatopsia for there to be an increased chance to have a child with symptoms; this is known as autosomal recessive inheritance. Carrier testing of your partner or donor is recommended in addition to consultation with a genetic counselor for a more detailed risk assessment.
Since this is an inherited gene change, this information may be helpful to share with family members as it may impact their family planning.
Achromatopsia is a non-progressive inherited disorder characterized by partial or complete loss of color vision. Affected individuals can only see black, white, and various shades of gray. Individuals with milder achromatopsia may have only partial loss of color vision that allows for some color. Additional signs and symptoms can include an intolerance to bright light, uncontrollable eye movements, and a reduced sharpness of image (low visual acuity). It is important to note that achromatopsia is different from red-green color blindness, a condition where individuals can perceive color but have difficulties differentiating the colors from each other.
Life expectancy is not affected by a diagnosis of achromatopsia; however, quality of life can be affected. Depending on the severity of visual acuity, individuals with achromatopsia may benefit from preferential seating in classrooms, low-vision aids, or attending a specialized school equipped to assist students that have varying degrees of visual impairments.
Dark-tinted glasses improve the visual acuity of affected individuals, but there is no cure. Low-vision and occupational aids can assist individuals with achromatopsia in everyday living.
