Variant summary

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

The NM_014208.3(DSPP):c.1060C>T(p.Arg354Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00497 in 1,613,718 control chromosomes in the GnomAD database, including 39 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 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. R354H) has been classified as Uncertain significance.

Genes affected

DSPP (HGNC:3054): (dentin sialophosphoprotein) This gene encodes a member of the small integrin-binding ligand N-linked glycoprotein (SIBLING) family of proteins. The encoded preproprotein is secreted by odontoblasts and proteolytically processed to generate two principal proteins of the dentin extracellular matrix of the tooth, dentin sialoprotein and dentin phosphoprotein. These two protein products may play distinct but related roles in dentin mineralization. Mutations in this gene are associated with dentinogenesis imperfecta and dentin dysplasia. This gene is present in a gene cluster on chromosome 4. Allelic differences due to repeat polymorphisms have been found for this gene. [provided by RefSeq, Jan 2016]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.0036010146).

BP6

Variant 4-87613246-C-T is Benign according to our data. Variant chr4-87613246-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 260354.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00369 (562/152178) while in subpopulation SAS AF = 0.00998 (48/4808). AF 95% confidence interval is 0.00774. There are 3 homozygotes in GnomAd4. There are 291 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 562 AD,Unknown gene.
