Collection Method: clinical testing

The c.1394C>T (p.T465I) alteration is located in exon 4 (coding exon 4) of the BTBD3 gene. This alteration results from a C to T substitution at nucleotide position 1394, causing the threonine (T) at amino acid position 465 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
