Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2024The c.1271C>G (p.S424C) alteration is located in exon 8 (coding exon 7) of the IQUB gene. This alteration results from a C to G substitution at nucleotide position 1271, causing the serine (S) at amino acid position 424 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
