Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.452G>C (p.G151A) alteration is located in exon 7 (coding exon 6) of the TMEM175 gene. This alteration results from a G to C substitution at nucleotide position 452, causing the glycine (G) at amino acid position 151 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
