Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.1994G>A (p.R665Q) alteration is located in exon 9 (coding exon 9) of the KLHL1 gene. This alteration results from a G to A substitution at nucleotide position 1994, causing the arginine (R) at amino acid position 665 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
