Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 25, 2023The c.369G>C (p.E123D) alteration is located in exon 4 (coding exon 4) of the CRTC1 gene. This alteration results from a G to C substitution at nucleotide position 369, causing the glutamic acid (E) at amino acid position 123 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
