Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.181A>G (p.I61V) alteration is located in exon 3 (coding exon 3) of the IQCH gene. This alteration results from a A to G substitution at nucleotide position 181, causing the isoleucine (I) at amino acid position 61 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
