Deletions of one or more exons

Variant Reference
Combined deletion of BCAP31 and ABCD1 “Contiguous ABCD1 DXS1357E deletion syndrome” (CADDS). First described by Corzo et al. in 2002. The combined deletion of the BCAP31 and ABCD1 genes results in clinical symptoms and initial biochemical results that are consistent with a peroxisomal biogenesis disorder (PBD).
0.5 kb in exon 1 Pathogenic, identified in 2 ALD patients (12).
exon 1 partial deletion Pathogenic, identified in 2 ALD patients (33).
exon 1 partial – exon 2 Pathogenic, identified in ALD patient (171).
exon1-2del Pathogenic, identified in ALD patient (90).
exon1-5del Pathogenic, identified in 2 ALD patients (33, 49). No detectable ALDP in patient cells (33).
exon2del Pathogenic, identified in 3 ALD patients (18, 88, 140). No detectable ALDP in patient cells (58).
exon2-8del Pathogenic, identified in 3 ALD patients (18). No detectable ALDP in patient cells (58).
exon3-5del Pathogenic, identified in 5 ALD patients (18, 33, 120).
exon3-6del Pathogenic, identified in ALD patient (33).
exon3-7del Pathogenic, identified in ALD patient (33).
exon3-10del Pathogenic, identified in 11 ALD patients (12, 13, 29, 33, 88). No detectable ALDP in patient cells (33).
exon5del Pathogenic, identified in 3 ALD patients (33, 88, 143).
exon5-6del Pathogenic, identified in ALD patient (18). No detectable ALDP in patient cells (58).
exon6del Pathogenic, identified in ALD patient (33).
exon6-9del Pathogenic, identified in 2 ALD patients (32).
exon6-10del Pathogenic, identified in 4 ALD patients (12, 24, 33).
exon7-9del Pathogenic, identified in ALD patient (24).
exon7-10del Pathogenic, identified in 15 ALD patients (13, 18, 22, 98). No detectable ALDP in patient cells (22).
exon8-9del Pathogenic, identified in ALD patient (18). No detectable ALDP in patient cells (58).
exon8-10del Pathogenic, identified in 19 ALD patients (13, 32, 33, 88, 98, 141). No detectable ALDP in patient cells (141).
multiple exons Pathogenic, identified in ALD patient (23).

Legend: The column headed “ALDP” indicates the effect of the mutation on the ALD protein assessed in fibroblasts by immunofluorescence and /or protein blot analysis. (n.d.) = unknown, no data provided.
Note: unpublished mutations (unpublished data) may not be used for publication purposes without prior approval from the editor of the database and the laboratories/investigators that have identified these mutations.
