Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.1922A>T (p.D641V) alteration is located in exon 18 (coding exon 17) of the CATSPERB gene. This alteration results from a A to T substitution at nucleotide position 1922, causing the aspartic acid (D) at amino acid position 641 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
