Short answer · Medically reviewed summary · Last updated: 2026-05-08
Fraser Syndrome is a rare genetic disorder typically diagnosed at birth due to characteristic physical features, most notably cryptophthalmos (skin-covered eyes). Because Fraser Syndrome is a congenital condition present from birth, it is not a condition that develops in adulthood, though individuals may manage its long-term health impacts throughout their lives. What are the primary indicators of Fraser Syndrome? The hallmark sign of Fraser Syndrome is cryptophthalmos, where the eyelids fail to separate and are instead covered by skin.

Fraser Syndrome is a rare genetic disorder typically diagnosed at birth due to characteristic physical features, most notably cryptophthalmos (skin-covered eyes). Because Fraser Syndrome is a congenital condition present from birth, it is not a condition that develops in adulthood, though individuals may manage its long-term health impacts throughout their lives.
What are the primary indicators of Fraser Syndrome?
The hallmark sign of Fraser Syndrome is cryptophthalmos, where the eyelids fail to separate and are instead covered by skin. Other clinical indicators frequently observed in infants with Fraser Syndrome include syndactyly (webbed fingers or toes), abnormal genitalia, and laryngeal stenosis, which can cause breathing difficulties. If you are concerned about symptoms in a newborn, these physical features are usually identified by neonatologists immediately after delivery.
How is Fraser Syndrome diagnosed?
Diagnosis of Fraser Syndrome is primarily clinical, based on the presence of specific physical features. To confirm the diagnosis, medical professionals typically utilize:
- Clinical examination: Assessing the eyes, genitalia, and extremities.
- Genetic testing: Identifying pathogenic variants in the FRAS1, FREM2, or GRIP1 genes.
- Imaging: Ultrasound or MRI to evaluate internal organ development, such as renal agenesis (missing kidneys).
When should I seek medical consultation?
If you or a family member have concerns regarding the genetic inheritance of Fraser Syndrome, it is essential to consult with a clinical geneticist. Because Fraser Syndrome follows an autosomal recessive inheritance pattern, parents of an affected child have a 25% chance of recurrence in future pregnancies. If you are an adult wondering if you have this condition, please note that it is rare for someone to reach adulthood without a formal diagnosis, as the physical manifestations are usually profound and present at birth.
