Genetic Variant NM_152499.4:c.245G>T (chr1-43992330-G-T) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_152499.4(CCDC24):c.245G>T(p.Arg82Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R82H) has been classified as Uncertain significance.

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]

CCDC24 links:

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]
