The c.866C>T (p.P289L) alteration is located in exon 7 (coding exon 7) of the FAM131B gene. This alteration results from a C to T substitution at nucleotide position 866, causing the proline (P) at amino acid position 289 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
