The c.911C>T (p.T304M) alteration is located in exon 7 (coding exon 7) of the GRTP1 gene. This alteration results from a C to T substitution at nucleotide position 911, causing the threonine (T) at amino acid position 304 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
