	abstract = {Background: Multiple congenital anomalies-hypotony-seizures syndrome 3 (MCAHS3) is a rare autosomal recessive disorder caused by mutations in the PIGT gene. PIGT encodes phosphatidylinositol-glycan biosynthesis class T, which plays a crucial role in protein anchoring to cell membranes. The clinical presentation of MCAHS3 is variable in expression and severity, but can be characterized by developmental delay, seizures, hypotonia, facial dysmorphism, and other abnormalities.Materials and Methods: Case report.Results: We report unusual ocular findings including bilateral anterior segment dysgenesis, avascular retinal periphery, and tractional retinal detachment in a 1-month-old male infant with compound heterozygous PIGT mutations consistent with MCAHS3. Whole-exome sequencing did not detect any other genetic abnormalities.Conclusions: This case expands the clinical spectrum of MCAHS3 to include anomalies in ocular anterior segment and retinal vascular development. Given the rarity and the genetic heterogeneity of MCAHS3, giving rise to varied non-ocular phenotypes, it is possible that milder intraocular phenotypes could have gone unrecognized in the past.},
