Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.1366C>T (p.R456C) 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 1366, causing the arginine (R) at amino acid position 456 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
