The c.321A>C (p.Q107H) alteration is located in exon 3 (coding exon 3) of the LAMP5 gene. This alteration results from a A to C substitution at nucleotide position 321, causing the glutamine (Q) at amino acid position 107 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
