Evidence submitted by expert panel
Congenital Myopathies VCEP
The NM_001100.4:c.809-35del variant in ACTA1 is an intronic variant which is located in the 3’ non-canonical splice site of intron 5. The population filtering allele frequency in gnomAD v4.1.0 is 0.2723 (20520/74490 alleles with 2805 homozygotes) in the African/African American population, which is higher than the ClinGen Congenital Myopathies VCEP threshold for BA1, and therefore meets this criterion (BA1). The results from the in silico predictor, SpliceAI, suggest that the variant does not impact ACTA1 function and it occurs at a nucleotide that is not conserved as shown by the UCSC Browser (BP4, BP7). In summary, this variant meets the criteria to be classified as benign for alpha-actinopathy based on the ACMG/AMP criteria applied, as specified by the ClinGen Congenital Myopathies VCEP: BA1, BP7 (ClinGen Congenital Myopathies VCEP specifications version 1; 08/07/2024).

BA1
The population filtering allele frequency in gnomAD v4.1.0 is 0.2723 (20520/74490 alleles with 2805 homozygotes) in the African/African American population, which is higher than the ClinGen Congenital Myopathies VCEP threshold for BA1, and therefore meets this criterion.
BP7
The results from the in silico predictor, SpliceAI, suggest that the variant does not impact ACTA1 function and it occurs at a nucleotide that is not conserved as shown by the UCSC Browser (BP4, BP7).
BP4
The results from the in silico predictor, SpliceAI, suggest that the variant does not impact ACTA1 function and it occurs at a nucleotide that is not conserved as shown by the UCSC Browser (BP4, BP7).
