Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.2233A>G (p.I745V) alteration is located in exon 11 (coding exon 11) of the KLHL1 gene. This alteration results from a A to G substitution at nucleotide position 2233, causing the isoleucine (I) at amino acid position 745 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
