Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2024The c.487C>T (p.P163S) 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 487, causing the proline (P) at amino acid position 163 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
