Genes affected
SBF2 (HGNC:2135): (SET binding factor 2) This gene encodes a pseudophosphatase and member of the myotubularin-related protein family. This gene maps within the CMT4B2 candidate region of chromosome 11p15 and mutations in this gene have been associated with Charcot-Marie-Tooth Disease, type 4B2. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.4).
BP6
Variant 11-10193914-C-T is Benign according to our data. Variant chr11-10193914-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 301928.
BP7
Synonymous conserved (PhyloP=1.5 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000113 (165/1458458) while in subpopulation NFE AF = 0.000143 (159/1109036). AF 95% confidence interval is 0.000125. There are 0 homozygotes in GnomAdExome4. There are 80 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check.
