Genes affected

DMD (HGNC:2928): (dystrophin) This gene spans a genomic range of greater than 2 Mb and encodes a large protein containing an N-terminal actin-binding domain and multiple spectrin repeats. The encoded protein forms a component of the dystrophin-glycoprotein complex (DGC), which bridges the inner cytoskeleton and the extracellular matrix. Deletions, duplications, and point mutations at this gene locus may cause Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), or cardiomyopathy. Alternative promoter usage and alternative splicing result in numerous distinct transcript variants and protein isoforms for this gene. [provided by RefSeq, Dec 2016]

The DMD c.7597G>A; p.Ala2533Thr variant (rs369583884), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 569218). This variant is found in the South Asian population with an allele frequency of 0.02% (4/19078 alleles, including a single hemizygote) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is neutral (REVEL: 0.141). Due to limited information, the clinical significance of this variant is uncertain at this time. -

Collection Method:clinical testing

The p.A2533T variant (also known as c.7597G>A), located in coding exon 52 of the DMD gene, results from a G to A substitution at nucleotide position 7597. The alanine at codon 2533 is replaced by threonine, an amino acid with similar properties. Based on data from gnomAD, the A allele has an overall frequency of 0.0027% (5/183506) total alleles studied, with 1 hemizygote(s) observed. The highest observed frequency was 0.0221% (1/4533) of 'Other' alleles. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. -
