Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2
The NM_001099922.3(ALG13):c.10G>A(p.Val4Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,210,761 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 5 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. V4V) has been classified as Likely benign.

Submissions by phenotype
Developmental and epileptic encephalopathy, 36 Uncertain:1
This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 4 of the ALG13 protein (p.Val4Met). This variant is present in population databases (no rsID available, gnomAD 0.001%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with ALG13-related conditions. ClinVar contains an entry for this variant (Variation ID: 1041615). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
