Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 1P and 5B. PP2BP4BS2

The NM_001130823.3(DNMT1):​c.3262G>T​(p.Val1088Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000435 in 1,611,028 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V1088I) has been classified as Likely benign.

Genes affected
DNMT1 (HGNC:2976): (DNA methyltransferase 1) This gene encodes an enzyme that transfers methyl groups to cytosine nucleotides of genomic DNA. This protein is the major enzyme responsible for maintaining methylation patterns following DNA replication and shows a preference for hemi-methylated DNA. Methylation of DNA is an important component of mammalian epigenetic gene regulation. Aberrant methylation patterns are found in human tumors and associated with developmental abnormalities. Variation in this gene has been associated with cerebellar ataxia, deafness, and narcolepsy, and neuropathy, hereditary sensory, type IE. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DNMT1. . Gene score misZ 4.9903 (greater than the threshold 3.09). Trascript score misZ 7.3302 (greater than threshold 3.09). GenCC has associacion of gene with hereditary sensory neuropathy-deafness-dementia syndrome, autosomal dominant cerebellar ataxia, deafness and narcolepsy.
BP4
Computational evidence support a benign effect (MetaRNN=0.34673917).
BS2
High AC in GnomAdExome4 at 6 AD gene.
