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 (BayesDel_noAF=-0.69).
BP6
Variant 10-68199581-G-A is Benign according to our data. Variant chr10-68199581-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 380682.
BS1
Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.00000684 (10/1461010) while in subpopulation AFR AF = 0.000179 (6/33466). AF 95% confidence interval is 0.0000771. There are 0 homozygotes in GnomAdExome4. There are 7 alleles in the male GnomAdExome4 subpopulation. Median coverage is 40. This position passed quality control check.
