Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.539C>T (p.T180M) alteration is located in exon 6 (coding exon 6) of the CNN1 gene. This alteration results from a C to T substitution at nucleotide position 539, causing the threonine (T) at amino acid position 180 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
