The c.259C>G (p.P87A) alteration is located in exon 1 (coding exon 1) of the LSM11 gene. This alteration results from a C to G substitution at nucleotide position 259, causing the proline (P) at amino acid position 87 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
