Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.173C>T (p.T58M) alteration is located in exon 3 (coding exon 2) of the TMEM175 gene. This alteration results from a C to T substitution at nucleotide position 173, causing the threonine (T) at amino acid position 58 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
