Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.1517T>C (p.M506T) alteration is located in exon 9 (coding exon 8) of the IQUB gene. This alteration results from a T to C substitution at nucleotide position 1517, causing the methionine (M) at amino acid position 506 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
