The c.395C>T (p.S132L) alteration is located in exon 3 (coding exon 3) of the FAM159B gene. This alteration results from a C to T substitution at nucleotide position 395, causing the serine (S) at amino acid position 132 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
