Ambry Genetics

Sep 16, 2021

The c.281T>C (p.L94P) alteration is located in exon 2 (coding exon 1) of the ANKAR gene. This alteration results from a T to C substitution at nucleotide position 281, causing the leucine (L) at amino acid position 94 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
