Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2024The c.1174G>C (p.D392H) alteration is located in exon 8 (coding exon 8) of the KLHL18 gene. This alteration results from a G to C substitution at nucleotide position 1174, causing the aspartic acid (D) at amino acid position 392 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
