We conclude from the very low penetrance and genetic epidemiological analyses that c.1103G>A (p.R368H) is unlikely to be a disease-causing recessive mutation in congenital glaucoma as previously reported.
To search for potential phenotypic modifiers regulating secretion of GDF5, we compared cells overexpressing wild type (Wt) GDF5 and GDF5 with a novel mutation in the prodomain identified in a large Pakistani family with Brachydactyly type C and mild Grebe type chondrodyslplasia (c527T>C; p.Leu176Pro).
Heterozygous c.1642C >T (p.Arg548*) possibly contributed to MFS-related phenotypes, including ocular manifestations, mitral valve prolapse, and pectus excavatum, but was not cause of MFS.

Homozygous c.3529G>A (p.Val1177Met) was shown to cause autosomal recessive WMS or WM-like syndrome by several approaches, including homozygosity mapping.
The genetically homogeneous group of p.R299X homozygotes showed variable phenotypes (presumably also underlying pathogenetic mechanisms), wherein PCG proper with primary dysgenesis of the trabecular meshwork, and Marfan syndrome-like zonular disease with ectopia lentis and later onset secondary glaucoma are two extremes.
