Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 29, 2023The c.734C>T (p.T245M) alteration is located in exon 6 (coding exon 6) of the TMEM39B gene. This alteration results from a C to T substitution at nucleotide position 734, causing the threonine (T) at amino acid position 245 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
