Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 23, 2023The c.583C>G (p.L195V) alteration is located in exon 6 (coding exon 4) of the IQCG gene. This alteration results from a C to G substitution at nucleotide position 583, causing the leucine (L) at amino acid position 195 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
