The c.757A>G (p.T253A) alteration is located in exon 9 (coding exon 9) of the FAM92B gene. This alteration results from a A to G substitution at nucleotide position 757, causing the threonine (T) at amino acid position 253 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
