The c.2968C>G (p.P990A) alteration is located in exon 1 (coding exon 1) of the POM121L2 gene. This alteration results from a C to G substitution at nucleotide position 2968, causing the proline (P) at amino acid position 990 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
