Collection Method:clinical testing

The c.161C>T (p.S54L) alteration is located in exon 2 (coding exon 2) of the FAM69B gene. This alteration results from a C to T substitution at nucleotide position 161, causing the serine (S) at amino acid position 54 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
