Haji-Seyed-Javadi et al 2012 Hum Mutat 33:1182 PMID:22539340 identified homozygous c.3529G>A (p.Val1177Met) in a patient with Weill-Marchesani syndrome and c.1642C >T (p.Arg548*) in a patient with Marfan syndrome. They comment that p.Arg548* may be contributing to MFS-related phenotypes but is not responsible for the MFS in that patient (abstract only). Two other variants associated with MFS on HGMD but these are in unavailable conference abstract. Don't think sufficient evidence for this gene.Created: 25 Mar 2019, 4:27 p.m.
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
On the Inherited Cardiac Condition Genes panel for Marfan syndrome reported in: Development of a Comprehensive Sequencing Assay for Inherited Cardiac Condition Genes, Pua et al, Journal of Cardiovascular Translational Research, online Feb 2016 (doi:10.1007/s12265-016-9673-5). The panel contains disease-causing, putatively pathogenic, research and phenocopy genes, and it is unclear from the publication whether this gene falls into the disease-causing category. No. of mutations indicated in supplemental table = 3.
