Our verdict is Benign. Variant got -14 ACMG points: 0P and 14B. BP4_ModerateBP6_Very_StrongBS2
The NM_001386795.1(DTNA):c.51G>A(p.Gln17Gln) variant causes a synonymous change. The variant allele was found at a frequency of 0.000155 in 1,613,270 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★).
DTNA (HGNC:3057): (dystrobrevin alpha) The protein encoded by this gene belongs to the dystrobrevin subfamily of the dystrophin family. This protein is a component of the dystrophin-associated protein complex (DPC), which consists of dystrophin and several integral and peripheral membrane proteins, including dystroglycans, sarcoglycans, syntrophins and alpha- and beta-dystrobrevin. The DPC localizes to the sarcolemma and its disruption is associated with various forms of muscular dystrophy. Mutations in this gene are associated with left ventricular noncompaction with congenital heart defects. Multiple alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]
Computational evidence support a benign effect (BayesDel_noAF=-0.44).

The p.Gln17Gln variant in DTNA variant is classified as likely benign because it does not alter an amino acid residue, is not located within the splice consensu s sequence, and computational tools do not suggest a splicing impact. It has bee n identified in 0.02% (71/276606) of chromosomes by the Genome Aggregation Datab ase (gnomAD; http://gnomad.broadinstitute.org; dbSNP rs368000651).
