Ambry Genetics

Jul 13, 2022

The c.11T>G (p.L4R) alteration is located in exon 1 (coding exon 1) of the CWH43 gene. This alteration results from a T to G substitution at nucleotide position 11, causing the leucine (L) at amino acid position 4 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
