Abstract:
Here we report an 18-year-old male patient with bilateral ectopia lentis and biallelic CPAMD8 variants (NM_015692.5:c.[2801delG];[4552C>T]; NP_056507.3:p.[(Gly934GlufsTer64)];[(Gln1518Ter)]). He exhibited previously unreported extraocular features, including a slender build, scoliosis, arachnodactyly and positive thumb sign and wrist sign, which is reminiscent of Marfan syndrome. These findings may suggest that CPAMD8-related disorder is a syndromic condition associated with extraocular systemic features similar to those seen in Marfan syndrome.
