Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.997A>G (p.S333G) alteration is located in exon 10 (coding exon 10) of the CRTC1 gene. This alteration results from a A to G substitution at nucleotide position 997, causing the serine (S) at amino acid position 333 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
