Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.1315C>G (p.R439G) alteration is located in exon 8 (coding exon 8) of the IKZF4 gene. This alteration results from a C to G substitution at nucleotide position 1315, causing the arginine (R) at amino acid position 439 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
