Ambry Genetics | RCV004109067 | SCV003578242 | uncertain significance | not specified | 2021-12-03 | criteria provided, single submitter | clinical testing | The c.565G>A (p.G189S) alteration is located in exon 3 (coding exon 3) of the NCDN gene. This alteration results from a G to A substitution at nucleotide position 565, causing the glycine (G) at amino acid position 189 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV004818261 | SCV005438994 | uncertain significance | Neurodevelopmental disorder with infantile epileptic spasms | 2023-07-22 | criteria provided, single submitter | clinical testing | The missense c.565G>Ap.Gly189Ser variant in NCDN gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Gly189Ser variant is present with allele frequency of 0.004% in gnomAD Exomes. This variant has not been submitted to the ClinVar database. Multiple lines of computational evidences Polyphen - Possibly damaging, SIFT - Tolerated and MutationTaster - Disease causing predict conflicting evidence on protein structure and function for this variant. The reference amino acid at this position on NCDN gene is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Gly at position 189 is changed to a Ser changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as a Variant of Uncertain Significance VUS. |
