The c.469G>A (p.A157T) alteration is located in exon 7 (coding exon 5) of the TMEM98 gene. This alteration results from a G to A substitution at nucleotide position 469, causing the alanine (A) at amino acid position 157 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
