The c.170C>A (p.A57E) alteration is located in exon 1 (coding exon 1) of the LSM11 gene. This alteration results from a C to A substitution at nucleotide position 170, causing the alanine (A) at amino acid position 57 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
