The c.392T>C (p.V131A) alteration is located in exon 6 (coding exon 4) of the SAMD3 gene. This alteration results from a T to C substitution at nucleotide position 392, causing the valine (V) at amino acid position 131 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
