Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.1504G>A (p.E502K) alteration is located in exon 12 (coding exon 12) of the IQCH gene. This alteration results from a G to A substitution at nucleotide position 1504, causing the glutamic acid (E) at amino acid position 502 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
