Ambry Genetics

Feb 28, 2024

The c.28C>T (p.R10C) alteration is located in exon 1 (coding exon 1) of the IKZF4 gene. This alteration results from a C to T substitution at nucleotide position 28, causing the arginine (R) at amino acid position 10 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
