Description
The p.P560L pathogenic mutation (also known as c.1679C>T), located in coding exon 7 of the ABCD1 gene, results from a C to T substitution at nucleotide position 1679. The proline at codon 560 is replaced by leucine, an amino acid with similar properties. This mutation has been reported in multiple affected males with the childhood cerebral form of X-linked adrenoleukodystrophy and adrenomyeloneuropathy (AMN) (Braun A et al. Am. J. Hum. Genet., 1995 Apr;56:854-61; Feigenbaum V et al. Am. J. Hum. Genet., 1996 Jun;58:1135-44; Shukla P et al. Clin. Chim. Acta, 2011 Nov;412:2289-95; Wang Y et al. Mol. Genet. Metab. Jun;104:160-6; Park HJ et al. Yonsei Med. J., 2014 May;55:676-82; Jack GH et al. Case Rep Neurol Med, 2013 Jun;2013:491790). In addition, adrenoleukodystrophy protein (ALDP) analysis in cells from affected individuals demonstrated a reduced level or absent protein compared to wild type (Feigenbaum V et al. Am. J. Hum. Genet., 1996 Jun;58:1135-44). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.
