The c.100A>G (p.T34A) alteration is located in exon 2 (coding exon 1) of the CGN gene. This alteration results from a A to G substitution at nucleotide position 100, causing the threonine (T) at amino acid position 34 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
