Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_001098785.2(FAM89B):​c.205G>T​(p.Ala69Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000583 in 1,199,878 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict 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. A69V) has been classified as Uncertain significance.

Genes affected

FAM89B (HGNC:16708): (family with sequence similarity 89 member B) Predicted to enable transcription corepressor binding activity. Predicted to be involved in establishment of cell polarity; negative regulation of transmembrane receptor protein serine/threonine kinase signaling pathway; and positive regulation of cell migration. Predicted to be active in cytoplasm and lamellipodium. [provided by Alliance of Genome Resources, Apr 2022]

ZNRD2 (HGNC:11328): (zinc ribbon domain containing 2) This antigen is recognized by a subset of anti-centromere antibodies from patients with scleroderma and/or Sjogren's syndrome. Subcellular localization has not yet been established. [provided by RefSeq, Jul 2008]

ZNRD2-DT (HGNC:27384): (ZNRD2 divergent transcript)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.043525457).
