Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.1460C>T (p.T487I) alteration is located in exon 13 (coding exon 13) of the CASC1 gene. This alteration results from a C to T substitution at nucleotide position 1460, causing the threonine (T) at amino acid position 487 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
