Feb 28, 2024

The c.400G>A (p.A134T) alteration is located in exon 3 (coding exon 3) of the MEDAG gene. This alteration results from a G to A substitution at nucleotide position 400, causing the alanine (A) at amino acid position 134 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
