Collection Method: clinical testing

The c.754G>T (p.A252S) alteration is located in exon 7 (coding exon 6) of the FAM114A2 gene. This alteration results from a G to T substitution at nucleotide position 754, causing the alanine (A) at amino acid position 252 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
