Variant summary
Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1
The NM_001164508.2(NEB):c.4407G>C(p.Glu1469Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0193 in 1,613,902 control chromosomes in the GnomAD database, including 428 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in UniProt.

ClinVar
Submissions by phenotype
not specified Benign:7
Likely benign based on allele frequency in 1000 Genomes Project or ESP global frequency and its presence in a patient with a rare or unrelated disease phenotype. NOT Sanger confirmed. -
p.Glu1469Asp in exon 38 of NEB: This variant is not expected to have clinical si gnificance because it has been identified in 4.8% (198/4134) of African American chromosomes from a broad population by the NHLBI Exome Sequencing Project (http ://evs.gs.washington.edu/EVS; dbSNP rs34800215). -
Variant summary: NEB c.4407G>C (p.Glu1469Asp) results in a conservative amino acid change in the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.02 in 277192 control chromosomes in the gnomAD database, including 91 homozygotes. The observed variant frequency is approximately 6 fold of the estimated maximal expected allele frequency for a pathogenic variant in NEB causing Nemaline Myopathy 2 phenotype (0.0035), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.4407G>C in individuals affected with Nemaline Myopathy 2 and no experimental evidence demonstrating its impact on protein function have been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
