Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.5995G>C (p.V1999L) alteration is located in exon 34 (coding exon 32) of the PLXNB1 gene. This alteration results from a G to C substitution at nucleotide position 5995, causing the valine (V) at amino acid position 1999 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
