Genes affected
CCDC24 (HGNC:28688): (coiled-coil domain containing 24) Predicted to act upstream of or within blastocyst hatching. [provided by Alliance of Genome Resources, Apr 2022]
SLC6A9 (HGNC:11056): (solute carrier family 6 member 9) The amino acid glycine acts as an inhibitory neurotransmitter in the central nervous system. The protein encoded by this gene is one of two transporters that stop glycine signaling by removing it from the synaptic cleft. [provided by RefSeq, Jun 2016]

The c.88G>C (p.E30Q) alteration is located in exon 2 (coding exon 1) of the CCDC24 gene. This alteration results from a G to C substitution at nucleotide position 88, causing the glutamic acid (E) at amino acid position 30 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
