Collection Method: clinical testing

The c.235C>T (p.L79F) alteration is located in exon 2 (coding exon 2) of the FAM159B gene. This alteration results from a C to T substitution at nucleotide position 235, causing the leucine (L) at amino acid position 79 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
