Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.865C>G (p.H289D) alteration is located in exon 7 (coding exon 7) of the CNN1 gene. This alteration results from a C to G substitution at nucleotide position 865, causing the histidine (H) at amino acid position 289 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
