The c.464C>T (p.T155I) alteration is located in exon 5 (coding exon 5) of the GGH gene. This alteration results from a C to T substitution at nucleotide position 464, causing the threonine (T) at amino acid position 155 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
