Login to comment 86 ABCD1 p.Arg518Gln The already described p.Arg518Gln mutation [14] was found in three families from Rio Grande do Sul: one of these affected families was due to a de novo mutation in the maternal germ line. Login to comment 87 ABCD1 p.Arg518Gln We can not rule out the possibility that the other two p.Arg518Gln pedigrees have a common ancestral origin, given their geographical proximity.

Login to comment 91 ABCD1 p.Leu628Glu ABCD1 p.Pro623Leu ABCD1 p.Ile481Phe ABCD1 p.Arg401Gly PolyPhen analysis of the four novel missense mutations considered three of them to be ''probably damaging`` p.Arg401Gly (PSIC score 3.071), p.Pro623Leu (PSIC score 3.379), and p.Leu628Glu (PSIC score 2.417), whereas p.Ile481Phe was considered ''benign`` Figure 1. Login to comment 114 ABCD1 p.Gly510Ser Her VLCFA profile was highly suggestive of a heterozygous state for X-ALD; the molecular analysis revealed the presence of the mutation p.GLy510Ser in one of her alleles (Table 2). Login to comment 129 ABCD1 p.Arg518Gln Our rate of 34% of new mutations is in agreement with this overall picture, moreover if we remember that even the only recurrent mutation in our case series (p.Arg518Gln) has emerged at least once from a de novo phenomenon (Table 1 and Figure 2).
