Dec 14, 2022

The c.566C>T (p.T189I) alteration is located in exon 4 (coding exon 4) of the MGARP gene. This alteration results from a C to T substitution at nucleotide position 566, causing the threonine (T) at amino acid position 189 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
