Collection Method: clinical testing

The c.745G>A (p.A249T) alteration is located in exon 8 (coding exon 8) of the FAM92B gene. This alteration results from a G to A substitution at nucleotide position 745, causing the alanine (A) at amino acid position 249 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
