The c.586A>G (p.T196A) alteration is located in exon 3 (coding exon 3) of the CD101 gene. This alteration results from a A to G substitution at nucleotide position 586, causing the threonine (T) at amino acid position 196 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
