The c.6611C>T (p.T2204M) alteration is located in exon 35 (coding exon 35) of the AHCTF1 gene. This alteration results from a C to T substitution at nucleotide position 6611, causing the threonine (T) at amino acid position 2204 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
