Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.746C>T (p.T249M) alteration is located in exon 1 (coding exon 1) of the OR8J3 gene. This alteration results from a C to T substitution at nucleotide position 746, causing the threonine (T) at amino acid position 249 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
