The c.1349T>C (p.V450A) alteration is located in exon 1 (coding exon 1) of the SATL1 gene. This alteration results from a T to C substitution at nucleotide position 1349, causing the valine (V) at amino acid position 450 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
