Collection Method: clinical testing

The c.242C>T (p.A81V) alteration is located in exon 1 (coding exon 1) of the FAM49A gene. This alteration results from a C to T substitution at nucleotide position 242, causing the alanine (A) at amino acid position 81 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
