Collection Method: clinical testing

The c.97A>G (p.T33A) alteration is located in exon 1 (coding exon 1) of the FAM179B gene. This alteration results from a A to G substitution at nucleotide position 97, causing the threonine (T) at amino acid position 33 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
