Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2022The c.700G>A (p.A234T) alteration is located in exon 3 (coding exon 2) of the KLHL8 gene. This alteration results from a G to A substitution at nucleotide position 700, causing the alanine (A) at amino acid position 234 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
