Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2024The c.1949T>C (p.M650T) alteration is located in exon 16 (coding exon 16) of the CASC1 gene. This alteration results from a T to C substitution at nucleotide position 1949, causing the methionine (M) at amino acid position 650 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
