The c.2864C>T (p.P955L) alteration is located in exon 16 (coding exon 16) of the FAM184B gene. This alteration results from a C to T substitution at nucleotide position 2864, causing the proline (P) at amino acid position 955 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
