Collection Method: curation

The heterozygous p.Asp2703Glu variant in MYO15B was identified by our study in 1 individual with dysphagia, ptosis, increased muscle fatigability, and muscle weakness. This variant was detected in cis with another variant of uncertain significance (p.c.2651+2T>A) in MYO15B. While this gene is still lacking sufficient evidence to establish a gene-disease relationship, we believe this is a possible novel gene candidate for this phenotype. Given the limited information about this gene-disease relationship, the significance of the p.Asp2703Glu variant is uncertain. If you have any additional information about functional evidence or other individuals with this phenotype that also have variants in MYO15B we encourage you to reach out to us. -
