Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2022The c.543G>C (p.K181N) alteration is located in exon 1 (coding exon 1) of the KLHDC7B gene. This alteration results from a G to C substitution at nucleotide position 543, causing the lysine (K) at amino acid position 181 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
