The c.1537G>A (p.V513I) alteration is located in exon 12 (coding exon 10) of the SAMD3 gene. This alteration results from a G to A substitution at nucleotide position 1537, causing the valine (V) at amino acid position 513 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
