Genes affected
UNC13A (HGNC:23150): (unc-13 homolog A) This gene encodes a member of the UNC13 family. UNC13 proteins bind to phorbol esters and diacylglycerol and play important roles in neurotransmitter release at synapses. Single nucleotide polymorphisms in this gene may be associated with sporadic amyotrophic lateral sclerosis. [provided by RefSeq, Feb 2012]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), UNC13A. . Gene score misZ 5.6267 (greater than the threshold 3.09). Trascript score misZ 5.1925 (greater than threshold 3.09). GenCC has associacion of gene with congenital nervous system disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.18861997).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 22, 2023The c.4825G>A (p.D1609N) alteration is located in exon 44 (coding exon 44) of the UNC13A gene. This alteration results from a G to A substitution at nucleotide position 4825, causing the aspartic acid (D) at amino acid position 1609 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
