Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.1328A>T (p.Q443L) alteration is located in exon 8 (coding exon 7) of the IQUB gene. This alteration results from a A to T substitution at nucleotide position 1328, causing the glutamine (Q) at amino acid position 443 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
