Genes affected

KHDC3L (HGNC:33699): (KH domain containing 3 like, subcortical maternal complex member) The protein encoded by this gene belongs to the KHDC1 family, members of which contain an atypical KH domain that may not bind RNA like canonical KH domains. This gene is specifically expressed in the oocytes, and recent studies suggest that it may function as a regulator of genomic imprinting in the oocyte. Mutations in this gene are associated with recurrent biparental complete hydatidiform mole. [provided by RefSeq, Dec 2011]

Nov 29, 2023

The c.276G>T (p.R92S) alteration is located in exon 2 (coding exon 2) of the KHDC3L gene. This alteration results from a G to T substitution at nucleotide position 276, causing the arginine (R) at amino acid position 92 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
