The c.1621A>G (p.I541V) alteration is located in exon 13 (coding exon 13) of the STRN3 gene. This alteration results from a A to G substitution at nucleotide position 1621, causing the isoleucine (I) at amino acid position 541 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
