Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 1P and 9B. PP2BP4_StrongBP6BS2

The NM_017534.6(MYH2):ā€‹c.3127T>Gā€‹(p.Ser1043Ala) variant causes a missense change. The variant allele was found at a frequency of 0.00192 in 1,614,128 control chromosomes in the GnomAD database, including 8 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1043F) has been classified as Likely benign.

Genes affected
MYH2 (HGNC:7572): (myosin heavy chain 2) Myosins are actin-based motor proteins that function in the generation of mechanical force in eukaryotic cells. Muscle myosins are heterohexamers composed of 2 myosin heavy chains and 2 pairs of nonidentical myosin light chains. This gene encodes a member of the class II or conventional myosin heavy chains, and functions in skeletal muscle contraction. This gene is found in a cluster of myosin heavy chain genes on chromosome 17. A mutation in this gene results in inclusion body myopathy-3. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Sep 2009]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MYH2. . Gene score misZ 1.9724 (greater than the threshold 3.09). Trascript score misZ 4.733 (greater than threshold 3.09). GenCC has associacion of gene with childhood-onset autosomal recessive myopathy with external ophthalmoplegia, hereditary inclusion body myopathy-joint contractures-ophthalmoplegia syndrome, myopathy, proximal, and ophthalmoplegia.
BP4
Computational evidence support a benign effect (MetaRNN=0.023307532).
BP6
Variant 17-10529472-A-C is Benign according to our data. Variant chr17-10529472-A-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 195898.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=4, Uncertain_significance=2}.
BS2
High Homozygotes in GnomAdExome4 at 7 SD gene
