Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_198576.4(AGRN):​c.5353G>A​(p.Asp1785Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00951 in 1,566,410 control chromosomes in the GnomAD database, including 87 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D1785H) has been classified as Uncertain significance.

Genes affected
AGRN (HGNC:329): (agrin) This gene encodes one of several proteins that are critical in the development of the neuromuscular junction (NMJ), as identified in mouse knock-out studies. The encoded protein contains several laminin G, Kazal type serine protease inhibitor, and epidermal growth factor domains. Additional post-translational modifications occur to add glycosaminoglycans and disulfide bonds. In one family with congenital myasthenic syndrome affecting limb-girdle muscles, a mutation in this gene was found. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2015]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0104987025).
BP6
Variant 1-1051352-G-A is Benign according to our data. Variant chr1-1051352-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 128314.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=4}. Variant chr1-1051352-G-A is described in Lovd as [Benign].
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00677 (1030/152056) while in subpopulation NFE AF = 0.0115 (778/67918). AF 95% confidence interval is 0.0108. There are 1 homozygotes in GnomAd4. There are 447 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position FAILED quality control check.
BS2
