Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.536C>T (p.S179F) alteration is located in exon 3 (coding exon 3) of the BTNL8 gene. This alteration results from a C to T substitution at nucleotide position 536, causing the serine (S) at amino acid position 179 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
