The c.1038G>C (p.L346F) alteration is located in exon 9 (coding exon 9) of the NOC3L gene. This alteration results from a G to C substitution at nucleotide position 1038, causing the leucine (L) at amino acid position 346 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
