Genes affected
KLHDC8A (HGNC:25573): (kelch domain containing 8A) This gene encodes a kelch domain-containing protein which is upregulated in cancer. Upregulated expression of the encoded protein may provide an alternative pathway for tumors to maintain aggressiveness in the absence of epidermal growth factor receptor dependence. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2022The c.461T>C (p.M154T) alteration is located in exon 3 (coding exon 2) of the KLHDC8A gene. This alteration results from a T to C substitution at nucleotide position 461, causing the methionine (M) at amino acid position 154 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
