✦ Synopsis

We report 9 new mutations in German patients presenting with classical Marfan syndrome. All mutations occur in exons with calcium-binding (cb) epidermal growth factor-like (EGF) domains. Five mutations are missense involving exons 12, 27, 30, 44, and 52 with the resultant substitution of cysteine by phenylalanine (C504F), cysteine by tyrosine (C1129Y), tyrosine by cysteine (Y1261C), cysteine by serine (C1833S), and cysteine by tyrosine (C2142Y), respectively. The other four mutations are single base deletions in exons 39, 43, 48, and 58, at nucleotide A4826, C5311, T6018, and A7291, respectively, each resulting in frameshift with premature termination. Four mutations were detected in sporadic cases and are likely to be de novo.

Marfan Syndrome (MFS) is a connective tissue disease caused by mutations in the fibrillin-1 (FBN1) gene. Screening for mutations in all the 65 exons of the FBN1 gene in 34 unrelated patients were performed to compare the efficiency of SSCP versus Heteroduplex analysis and to verify if the spectrum o
