The heterozygous p.Arg229Trp variant in AFAP1L1 was identified by our study, in the compound heterozygous state with another variant of uncertain significance, in 1 individual with neuromuscular disease. While this gene is still lacking sufficient evidence to establish a gene-disease relationship, we believe this is a possible novel gene candidate for neuromuscular disease. Given the limited information about this gene-disease relationship, the significance of the AFAP1L1 variant is uncertain. If you have any additional information about functional evidence or other individuals with this phenotype that also have variants in AFAP1L1 we encourage you to reach out to us. -
