102 Variation in the immunoreactivity of the ALD mutant protein was observed for two mutations, P560L and R518W: immunoreactivity of mutant protein P560L was markedly decreased in fibroblasts and peripheral white blood cells from patients 69, 5, and 37 and was completely absent in patient 13. Login to comment
104 Similarly, ALDP immunoreactivity of mutant protein R518W was markedly decreased in fibroblasts from patient 76 and completely absent in fibroblasts from another patient (73) with the same mutation. Login to comment
134 Exceptions are a dinucleotide deletion (del 1801-1802) and P560L missense mutation, which were both observed in four kindreds, and S98L, R518W, and R660W missense mutations, which were each observed in two kindreds. Login to comment
140 In all cases, only one alteration was found, and except for the S98L, R518W, P560L, and R660W mutations, these alterations differed from each other. Login to comment
142 The R518W mutation occurred as a de novo mutation in one ALD patient, and the R518W and P560L mutations were not observed in 100 normal X chromosomes. Login to comment

173 Four missense mutations (S108W, P263L, R518W, and P560L) resulted in decreased ALDP immunoreactivity reflecting likely instability and/or partial deficiency in the peroxisomal targeting of ALDP. Login to comment

152 In contrast, the R591Q disease mutation, which alters the dimerization of ALDP in the yeast two-hybrid assays, does not lead to ALDP unstability in vivo. Login to comment
154 This is supported by the observation that several ALDP missense mutations (in particular R518W and P560L) can lead to either a normal, decreased level or absence of ALDP in ALD fibroblasts.4 The specific carboxyl-terminal subdomain region of ALDP responsible for dimerization could not be defined.

48 Asterisks indicate the posi- *l I U13 | tion of the four missense mutations in ALD protein (ALDP): R518W substitution occurs at the same amino acid position as in the CFTR mutant S1255P, and S606L at the same position as in the S5491 or S549R CFTR mutants; R617C and R617H have no equivalents in CFTR mutants.

81 This mutation (Arg 518 -+ Trp or R518W in the single letter amino acid code) (Fig. 3) causes a nonconservative change between a charged and strongly polar (basic) amino acid and a hydrophobic nonpolar amino acid (Fig. 1). Login to comment
