Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022The c.836C>G (p.S279C) alteration is located in exon 4 (coding exon 2) of the TCEANC gene. This alteration results from a C to G substitution at nucleotide position 836, causing the serine (S) at amino acid position 279 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
