Ambry Genetics

Oct 06, 2023

The c.194C>T (p.T65I) alteration is located in exon 2 (coding exon 1) of the BABAM1 gene. This alteration results from a C to T substitution at nucleotide position 194, causing the threonine (T) at amino acid position 65 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
