Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 19, 2024The c.365G>A (p.R122K) alteration is located in exon 5 (coding exon 5) of the IQCE gene. This alteration results from a G to A substitution at nucleotide position 365, causing the arginine (R) at amino acid position 122 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
