Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2023The c.1031T>A (p.V344E) alteration is located in exon 7 (coding exon 6) of the IQUB gene. This alteration results from a T to A substitution at nucleotide position 1031, causing the valine (V) at amino acid position 344 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
