Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.2006C>T (p.T669I) alteration is located in exon 19 (coding exon 18) of the CATSPERB gene. This alteration results from a C to T substitution at nucleotide position 2006, causing the threonine (T) at amino acid position 669 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
