The c.680C>T (p.T227M) alteration is located in exon 1 (coding exon 1) of the KIAA1671 gene. This alteration results from a C to T substitution at nucleotide position 680, causing the threonine (T) at amino acid position 227 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
