Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.440T>G (p.V147G) alteration is located in exon 4 (coding exon 4) of the IQCF1 gene. This alteration results from a T to G substitution at nucleotide position 440, causing the valine (V) at amino acid position 147 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
