Ambry Genetics

Nov 03, 2022

The c.161T>C (p.L54P) alteration is located in exon 2 (coding exon 2) of the SUN3 gene. This alteration results from a T to C substitution at nucleotide position 161, causing the leucine (L) at amino acid position 54 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
