The c.344T>C (p.L115P) alteration is located in exon 2 (coding exon 2) of the FAM163B gene. This alteration results from a T to C substitution at nucleotide position 344, causing the leucine (L) at amino acid position 115 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
