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]

SBF2-AS1 (HGNC:27438): (SBF2 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.51).
• BP6: Variant 11-9779327-C-T is Benign according to our data. Variant chr11-9779327-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 883673.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000243 (37/152308) while in subpopulation EAS AF = 0.00597 (31/5190). AF 95% confidence interval is 0.00432. There are 0 homozygotes in GnomAd4. There are 22 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
