The c.2573C>T (p.T858M) alteration is located in exon 7 (coding exon 6) of the SUGP2 gene. This alteration results from a C to T substitution at nucleotide position 2573, causing the threonine (T) at amino acid position 858 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
