Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.879A>T (p.L293F) alteration is located in exon 9 (coding exon 9) of the IQCH gene. This alteration results from a A to T substitution at nucleotide position 879, causing the leucine (L) at amino acid position 293 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
