Collection Method: clinical testing

The c.272C>G (p.A91G) alteration is located in exon 4 (coding exon 4) of the ATAD3C gene. This alteration results from a C to G substitution at nucleotide position 272, causing the alanine (A) at amino acid position 91 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
