Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.403C>G (p.R135G) alteration is located in exon 5 (coding exon 4) of the CSNK1G2 gene. This alteration results from a C to G substitution at nucleotide position 403, causing the arginine (R) at amino acid position 135 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
