Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.1808G>T (p.C603F) alteration is located in exon 15 (coding exon 15) of the IMMT gene. This alteration results from a G to T substitution at nucleotide position 1808, causing the cysteine (C) at amino acid position 603 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
