Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 03, 2022The c.146C>T (p.T49I) alteration is located in exon 3 (coding exon 3) of the SCNN1D gene. This alteration results from a C to T substitution at nucleotide position 146, causing the threonine (T) at amino acid position 49 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
