Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PVS1PM2PP5
The NM_001242896.3(DEPDC5):c.1909C>T(p.Arg637Ter) variant causes a stop gained change. The variant allele was found at a frequency of 0.0000589 in 1,614,048 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R637R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Oct 08, 2021 | Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Reported in the heterozygous state in one individual with nocturnal frontal lobe epilepsy (Ricos et al., 2016); This variant is associated with the following publications: (PMID: 27683934, 30093711, 26505888) - |
Inborn genetic diseases Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 11, 2021 | The c.1909C>T (p.R637*) alteration, located in exon 23 (coding exon 22) of the DEPDC5 gene, consists of a C to T substitution at nucleotide position 1909. This changes the amino acid from an arginine (R) to a stop codon at amino acid position 637. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This alteration has been reported in the heterozygous state in one individual with nocturnal frontal lobe epilepsy (Ricos, 2016). Based on the available evidence, this alteration is classified as pathogenic. - |
Familial focal epilepsy with variable foci Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 11, 2022 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 264735). This premature translational stop signal has been observed in individual(s) with nocturnal frontal lobe epilepsy (PMID: 26505888). This variant is present in population databases (rs780960812, gnomAD 0.004%). This sequence change creates a premature translational stop signal (p.Arg637*) in the DEPDC5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DEPDC5 are known to be pathogenic (PMID: 23542697, 23542701). - |
