Genes affected

MYRF (HGNC:1181): (myelin regulatory factor) This gene encodes a transcription factor that is required for central nervous system myelination and may regulate oligodendrocyte differentiation. It is thought to act by increasing the expression of genes that effect myelin production but may also directly promote myelin gene expression. Loss of a similar gene in mouse models results in severe demyelination. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MYRF. . Gene score misZ 3.2927 (greater than the threshold 3.09). Trascript score misZ 3.5469 (greater than threshold 3.09). GenCC has associacion of gene with encephalitis/encephalopathy, mild, with reversible myelin vacuolization, cardiac-urogenital syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.08777475).

BP6

Variant 11-61770306-G-A is Benign according to our data. Variant chr11-61770306-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3051447.Status of the report is no_assertion_criteria_provided, 0 stars.

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000533 (81/151850) while in subpopulation NFE AF= 0.000972 (66/67932). AF 95% confidence interval is 0.000783. There are 0 homozygotes in gnomad4. There are 36 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High AC in GnomAd4 at 81 AD gene.
