Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.134C>T (p.T45I) alteration is located in exon 2 (coding exon 2) of the ATAD3C gene. This alteration results from a C to T substitution at nucleotide position 134, causing the threonine (T) at amino acid position 45 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
