The c.1148C>T (p.T383M) alteration is located in exon 14 (coding exon 14) of the SUPT5H gene. This alteration results from a C to T substitution at nucleotide position 1148, causing the threonine (T) at amino acid position 383 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
