The c.319A>C (p.I107L) alteration is located in exon 5 (coding exon 5) of the PRELID2 gene. This alteration results from a A to C substitution at nucleotide position 319, causing the isoleucine (I) at amino acid position 107 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
