Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2024The c.2303T>G (p.I768S) alteration is located in exon 13 (coding exon 12) of the IQUB gene. This alteration results from a T to G substitution at nucleotide position 2303, causing the isoleucine (I) at amino acid position 768 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
