Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.916C>T (p.R306W) alteration is located in exon 2 (coding exon 1) of the LTB4R2 gene. This alteration results from a C to T substitution at nucleotide position 916, causing the arginine (R) at amino acid position 306 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
