The c.964C>T (p.P322S) alteration is located in exon 5 (coding exon 5) of the FAM117B gene. This alteration results from a C to T substitution at nucleotide position 964, causing the proline (P) at amino acid position 322 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
