Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.340C>T (p.R114W) alteration is located in exon 4 (coding exon 4) of the FAM129C gene. This alteration results from a C to T substitution at nucleotide position 340, causing the arginine (R) at amino acid position 114 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
