The c.324C>G (p.H108Q) alteration is located in exon 4 (coding exon 3) of the OSER1 gene. This alteration results from a C to G substitution at nucleotide position 324, causing the histidine (H) at amino acid position 108 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
