Genes affected
SPEG (HGNC:16901): (striated muscle enriched protein kinase) This gene encodes a protein with similarity to members of the myosin light chain kinase family. This protein family is required for myocyte cytoskeletal development. Along with the desmin gene, expression of this gene may be controlled by the desmin locus control region. Mutations in this gene are associated with centronuclear myopathy 5. [provided by RefSeq, Jun 2016]
ASIC4-AS1 (HGNC:40960): (ASIC4 antisense RNA 1)

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP3
Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.00021 (32/152224) while in subpopulation AMR AF = 0.000588 (9/15306). AF 95% confidence interval is 0.000306. There are 0 homozygotes in GnomAd4. There are 15 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
