Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1
The NM_004006.3(DMD):c.4162T>G(p.Phe1388Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00498 in 1,208,952 control chromosomes in the GnomAD database, including 158 homozygotes. There are 1,659 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 12/17 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in UniProt.

ClinVar
Submissions by phenotype
not specified Benign:8
- -
- -
- -
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Variant summary: DMD c.4162T>G (p.Phe1388Val) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0077 in 182914 control chromosomes in the gnomAD database, including 33 homozygotes and 364 hemizygotes. The observed variant frequency is approximately 695 fold of the estimated maximal expected allele frequency for a pathogenic variant in DMD causing Dystrophinopathies phenotype (1.1e-05), strongly suggesting that the variant is benign. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -
p.Phe1388Val in exon 30 of DMD: This variant is not expected to have clinical si gnificance because it has been identified in 9% (345/3833) of African American c hromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/E VS/; dbSNP rs28715870). -

Dilated cardiomyopathy 3B Benign:1
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
Cardiovascular phenotype Benign:1
This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
