Description

The p.W746C pathogenic mutation (also known as c.2238G>C), located in coding exon 15 of the GAA gene, results from a G to C substitution at nucleotide position 2238. The tryptophan at codon 746 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration has been reported in the compound heterozygous and homozygous states in individuals with Pompe disease, mainly late onset disease (Wan L et al. J Neurol, 2008 Jun;255:831-8; Chien YH et al. J Pediatr, 2011 Jun;158:1023-1027.e1; Yang CC et al. Mol Genet Metab, 2011 Nov;104:284-8; Fu Liong H et al. Case Rep Neurol Med, 2014 Jun;2014:926510; Liu X et al. BMC Med Genet, 2014 Dec;15:141; Chu YP et al. Neuromuscul Disord, 2016 Dec;26:873-879; Zhang B et al. Neuropsychiatr Dis Treat, 2016 Mar;12:713-7; Lee JH et al. Neuromuscul Disord, 2017 Jun;27:550-556; Park HJ et al. Clin Genet, 2017 Mar;91:403-410; Kim MS et al. Korean J Pediatr, 2019 Jun;62:224-234; Ficicioglu C et al. Int J Neonatal Screen, 2020 Nov;6:[ePub ahead of print]; Jia X et al. Aging (Albany NY), 2020 Mar;12:4268-4282; Sudrié-Arnaud B et al. Diagnostics (Basel), 2021 Feb;11:[ePub ahead of print]; Zhao HH et al. Ann Transl Med, 2021 Dec;9:1803; Si X et al. CNS Neurosci Ther, 2022 Oct;28:1651-1654; Zhang H et al. Front Neurol, 2022 Mar;13:839263). This alteration has also been shown to reduce enzyme activity in both patient-derived cells and transfected cells (Niño MY et al. JIMD Rep, 2013 Apr;7:39-48; Liu HX et al. Chin Med J (Engl), 2018 Feb;131:448-453). In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.
