Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 15, 2021The c.1163G>T (p.R388L) alteration is located in exon 5 (coding exon 5) of the TRMO gene. This alteration results from a G to T substitution at nucleotide position 1163, causing the arginine (R) at amino acid position 388 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
