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]

UNC13A Gene-Disease associations (from GenCC):

• congenital nervous system disorder

  Inheritance: Unknown Classification: LIMITED Submitted by: Illumina

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.171 is higher than 0.05.
