The c.851T>C (p.L284P) alteration is located in exon 9 (coding exon 9) of the GADL1 gene. This alteration results from a T to C substitution at nucleotide position 851, causing the leucine (L) at amino acid position 284 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
