Short answer · Medically reviewed summary · Last updated: 2026-05-08
Autosomal recessive multiple pterygium syndrome, also known as Escobar syndrome, is an ultra-rare genetic disorder with an estimated prevalence of less than 1 in 1,000,000 individuals worldwide. Due to its extreme rarity and the potential for clinical overlap with other conditions, accurate global incidence rates are currently unknown and likely underreported in medical literature. How common is Autosomal recessive multiple pterygium syndrome? Autosomal recessive multiple pterygium syndrome is classified as an ultra-rare condition.
What is the prevalence of Autosomal recessive multiple pterygium syndrome / Escobar syndrome?
Prevalence of Autosomal recessive multiple pterygium syndrome / Escobar syndrome: how many people are affected worldwide, differences by sex and region, with sources.
Autosomal recessive multiple pterygium syndrome, also known as Escobar syndrome, is an ultra-rare genetic disorder with an estimated prevalence of less than 1 in 1,000,000 individuals worldwide. Due to its extreme rarity and the potential for clinical overlap with other conditions, accurate global incidence rates are currently unknown and likely underreported in medical literature.
How common is Autosomal recessive multiple pterygium syndrome?
Autosomal recessive multiple pterygium syndrome is classified as an ultra-rare condition. Because there is no centralized global registry, exact prevalence figures remain speculative. Clinical data suggests that Escobar syndrome affects males and females equally, as the underlying genetic mutations are located on autosomal chromosomes rather than sex chromosomes. While the condition is congenital and present at birth, its clinical presentation can vary significantly in severity, sometimes leading to diagnostic delays.
What factors influence data accuracy for Escobar syndrome?
The rarity of Autosomal recessive multiple pterygium syndrome presents significant challenges for epidemiologists. Factors affecting our understanding of the true prevalence include:
- Underdiagnosis: Mild cases of Escobar syndrome may go unrecognized or be misattributed to other congenital neuromuscular disorders.
- Geographic Variability: While the syndrome has been reported globally, higher frequencies may appear in populations with higher rates of consanguinity, where autosomal recessive traits are more likely to manifest.
- Diagnostic Complexity: Overlap with lethal forms of multiple pterygium syndrome can complicate accurate classification in neonatal cases.
What is the community perspective on this condition?
While clinical literature provides the baseline, the DiseaseMaps.org community offers a vital real-world perspective. Currently, 2 members have joined the platform to share their experiences with Autosomal recessive multiple pterygium syndrome. Connecting with these individuals helps bridge the gap between abstract medical statistics and the lived reality of navigating life with Escobar syndrome.
Next steps
- Consult with a clinical geneticist to confirm a diagnosis through molecular testing.
