The IVNS1ABP c.934T>C variant is predicted to result in the amino acid substitution p.Phe312Leu. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
