The c.793G>T (p.V265L) alteration is located in exon 5 (coding exon 4) of the IGFLR1 gene. This alteration results from a G to T substitution at nucleotide position 793, causing the valine (V) at amino acid position 265 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
