Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.1294C>T (p.R432C) alteration is located in exon 10 (coding exon 10) of the KLHDC4 gene. This alteration results from a C to T substitution at nucleotide position 1294, causing the arginine (R) at amino acid position 432 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
