Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.2156G>A (p.R719Q) alteration is located in exon 15 (coding exon 15) of the IMMT gene. This alteration results from a G to A substitution at nucleotide position 2156, causing the arginine (R) at amino acid position 719 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
