• NM_006790.3:c.-211-125_-211-114dupCACACACACACA

Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BS1 BS2

The NM_006790.3(MYOT):​c.-211-125_-211-114dupCACACACACACA variant causes a intron change involving the alteration of a non-conserved nucleotide. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

MYOT (HGNC:12399): (myotilin) This gene encodes a cystoskeletal protein which plays a significant role in the stability of thin filaments during muscle contraction. This protein binds F-actin, crosslinks actin filaments, and prevents latrunculin A-induced filament disassembly. Mutations in this gene have been associated with limb-girdle muscular dystrophy and myofibrillar myopathies. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.[provided by RefSeq, Oct 2008]

PKD2L2-DT (HGNC:55557): (PKD2L2 divergent transcript)

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000787 (100/127080) while in subpopulation NFE AF = 0.00113 (69/60832). AF 95% confidence interval is 0.000919. There are 0 homozygotes in GnomAd4. There are 33 alleles in the male GnomAd4 subpopulation. Median coverage is 0. This position passed quality control check.
• BS2: High AC in GnomAd4 at 100 AD gene.
