Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.833C>T (p.T278M) alteration is located in exon 6 (coding exon 6) of the TMEM156 gene. This alteration results from a C to T substitution at nucleotide position 833, causing the threonine (T) at amino acid position 278 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
