Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.1266A>T (p.L422F) alteration is located in exon 4 (coding exon 2) of the KBTBD3 gene. This alteration results from a A to T substitution at nucleotide position 1266, causing the leucine (L) at amino acid position 422 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
