Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2023The c.385T>C (p.W129R) alteration is located in exon 3 (coding exon 3) of the TMEM42 gene. This alteration results from a T to C substitution at nucleotide position 385, causing the tryptophan (W) at amino acid position 129 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
