Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 24, 2023The c.565T>G (p.F189V) alteration is located in exon 3 (coding exon 3) of the BTNL8 gene. This alteration results from a T to G substitution at nucleotide position 565, causing the phenylalanine (F) at amino acid position 189 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
