Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.4344C>A (p.F1448L) alteration is located in exon 24 (coding exon 24) of the VWDE gene. This alteration results from a C to A substitution at nucleotide position 4344, causing the phenylalanine (F) at amino acid position 1448 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
