Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2024The c.2094G>A (p.M698I) alteration is located in exon 12 (coding exon 11) of the IQUB gene. This alteration results from a G to A substitution at nucleotide position 2094, causing the methionine (M) at amino acid position 698 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
