Genes affected

EBF2 (HGNC:19090): (EBF transcription factor 2) The protein encoded by this gene belongs to the COE (Collier/Olf/EBF) family of non-basic, helix-loop-helix transcription factors that have a well conserved DNA binding domain. The COE family proteins play an important role in variety of developmental processes. Studies in mouse suggest that this gene may be involved in the differentiation of osteoblasts.

LOC102723395 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.69).
• BP6: Variant 8-25861305-T-C is Benign according to our data. Variant chr8-25861305-T-C is described in ClinVar as [Benign]. Clinvar id is 789762.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0131 (1998/152324) while in subpopulation AFR AF= 0.0447 (1857/41564). AF 95% confidence interval is 0.043. There are 51 homozygotes in gnomad4. There are 965 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1998 AD gene.
