Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2022The c.86C>T (p.T29M) alteration is located in exon 2 (coding exon 1) of the TMEM239 gene. This alteration results from a C to T substitution at nucleotide position 86, causing the threonine (T) at amino acid position 29 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
