Description

The c.2381T>C (p.I794T) alteration is located in exon 18 (coding exon 18) of the SYNJ1 gene. This alteration results from a T to C substitution at nucleotide position 2381, causing the isoleucine (I) at amino acid position 794 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
