Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 26, 2022The c.892G>T (p.V298L) alteration is located in exon 2 (coding exon 1) of the LTB4R gene. This alteration results from a G to T substitution at nucleotide position 892, causing the valine (V) at amino acid position 298 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
