Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 28, 2024The c.862C>A (p.P288T) alteration is located in exon 6 (coding exon 6) of the IKZF4 gene. This alteration results from a C to A substitution at nucleotide position 862, causing the proline (P) at amino acid position 288 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
