The c.133G>A (p.A45T) alteration is located in exon 3 (coding exon 3) of the ZSWIM7 gene. This alteration results from a G to A substitution at nucleotide position 133, causing the alanine (A) at amino acid position 45 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
