Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBS1_SupportingBS2

The NM_198488.5(FAM83H):​c.3293G>T​(p.Ser1098Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000639 in 1,611,996 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1098N) has been classified as Uncertain significance.

Genes affected
FAM83H (HGNC:24797): (family with sequence similarity 83 member H) The protein encoded by this gene plays an important role in the structural development and calcification of tooth enamel. Defects in this gene are a cause of amelogenesis imperfecta type 3 (AI3). [provided by RefSeq, Mar 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.19090444).
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000664 (97/1459756) while in subpopulation NFE AF = 0.0000819 (91/1111606). AF 95% confidence interval is 0.0000679. There are 0 homozygotes in GnomAdExome4. There are 44 alleles in the male GnomAdExome4 subpopulation. Median coverage is 83. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 6 AD gene.
