Description

Gly21302Ser in exon 275 of TTN: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, dolphin, killer whale, white rhinoceros, manatee, and several bird specie h ave a serine (Ser) at this position despite high nearby amino acid conservation.
