Collection Method:clinical testing

The c.392C>G (p.S131C) alteration is located in exon 5 (coding exon 1) of the FAM110B gene. This alteration results from a C to G substitution at nucleotide position 392, causing the serine (S) at amino acid position 131 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
