Abstract EN
Loeys-Dietz syndrome (LDS) is a connective tissue disorder characterized by vascular findings of aneurysm and/or dissection of cerebral, thoracic, or abdominal arteries and skeletal findings.
We report a case of a novel pathogenic variant in TGFBR2 and phenotype consistent with classic LDS.
The proband was a 10-year-old presenting to the genetics clinic with an enlarged aortic root (Z-scores 5-6), pectus excavatum, and congenital contractures of the right 2nd and 3rd digit.
Molecular testing of TGFBR2 was sent to a commercial laboratory and demonstrated a novel, likely pathogenic, variant in exon 4, c.1061T>C, p.(L354P).
Molecular modeling reveals alteration of local protein structure as a result of this pathogenic variant.
This pathogenic variant has not been previously reported in LDS and thus expands the pathogenic variant spectrum of this condition.
