Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 14, 2022The c.5833C>T (p.R1945C) alteration is located in exon 33 (coding exon 31) of the PLXNB1 gene. This alteration results from a C to T substitution at nucleotide position 5833, causing the arginine (R) at amino acid position 1945 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
