Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.565C>T (p.R189C) alteration is located in exon 1 (coding exon 1) of the CNNM3 gene. This alteration results from a C to T substitution at nucleotide position 565, causing the arginine (R) at amino acid position 189 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
