Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 30, 2022The c.446C>T (p.T149M) alteration is located in exon 5 (coding exon 4) of the TMEM106C gene. This alteration results from a C to T substitution at nucleotide position 446, causing the threonine (T) at amino acid position 149 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
