Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2024The c.821C>T (p.T274M) alteration is located in exon 8 (coding exon 7) of the CSNK1G2 gene. This alteration results from a C to T substitution at nucleotide position 821, causing the threonine (T) at amino acid position 274 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
