Genes affected

MYPN (HGNC:23246): (myopalladin) Striated muscle in vertebrates comprises large proteins which must be organized properly to contract efficiently. Z-lines in striated muscle are a sign of this organization, representing the ends of actin thin filaments, titin, nebulin or nebulette and accessory proteins required for structure and function. This gene encodes a protein which interacts with nebulin in skeletal muscle or nebulette in cardiac muscle and alpha-actinin. In addition, this gene product can interact with a protein with the I-band indicating it has a regulatory as well as structural function. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.032969713).

BP6

Variant 10-68142989-G-A is Benign according to our data. Variant chr10-68142989-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 192124.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000184 (28/152122) while in subpopulation AMR AF = 0.000393 (6/15274). AF 95% confidence interval is 0.000171. There are 0 homozygotes in GnomAd4. There are 14 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
