Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.415C>T (p.R139W) alteration is located in exon 4 (coding exon 3) of the TMEM45B gene. This alteration results from a C to T substitution at nucleotide position 415, causing the arginine (R) at amino acid position 139 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
