Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.1178G>A (p.R393H) alteration is located in exon 9 (coding exon 9) of the IQCH gene. This alteration results from a G to A substitution at nucleotide position 1178, causing the arginine (R) at amino acid position 393 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
