Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.649A>G (p.K217E) alteration is located in exon 7 (coding exon 7) of the CRTC1 gene. This alteration results from a A to G substitution at nucleotide position 649, causing the lysine (K) at amino acid position 217 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
