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]

DMD-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesNov 11, 2022The DMD c.2972A>G variant is predicted to result in the amino acid substitution p.Glu991Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0012% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/X-32486805-T-C). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The p.E991G variant (also known as c.2972A>G), located in coding exon 23 of the DMD gene, results from an A to G substitution at nucleotide position 2972. The glutamic acid at codon 991 is replaced by glycine, an amino acid with similar properties. Based on data from gnomAD, the G allele has an overall frequency of <0.01% (1/181694) total alleles studied, with 0 hemizygote(s) observed. The highest observed frequency was <0.01% (1/80685) of European (non- Finnish) alleles. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
