Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.728C>T (p.P243L) alteration is located in exon 5 (coding exon 5) of the VWA5B2 gene. This alteration results from a C to T substitution at nucleotide position 728, causing the proline (P) at amino acid position 243 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
