Description

A homozygous TTN c.94648G>A (p.Glu31550Lys) missense variant was identified. This variant, to our knowledge, has not been reported in the medical literature and it is absent from the general population (gnomAD v.2.1.1), indicating it is not a common variant. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time.
