Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.137A>G (p.D46G) alteration is located in exon 1 (coding exon 1) of the TMEM196 gene. This alteration results from a A to G substitution at nucleotide position 137, causing the aspartic acid (D) at amino acid position 46 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
