Collection Method:clinical testing

The c.952T>G (p.C318G) alteration is located in exon 5 (coding exon 1) of the FAM110B gene. This alteration results from a T to G substitution at nucleotide position 952, causing the cysteine (C) at amino acid position 318 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
