Collection Method: clinical testing

The c.124C>A (p.L42I) alteration is located in exon 1 (coding exon 1) of the FAM159B gene. This alteration results from a C to A substitution at nucleotide position 124, causing the leucine (L) at amino acid position 42 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
