Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.2047A>G (p.M683V) alteration is located in exon 19 (coding exon 18) of the CATSPERB gene. This alteration results from a A to G substitution at nucleotide position 2047, causing the methionine (M) at amino acid position 683 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
