Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.614G>T (p.G205V) alteration is located in exon 5 (coding exon 5) of the FAM131A gene. This alteration results from a G to T substitution at nucleotide position 614, causing the glycine (G) at amino acid position 205 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
