Genes affected

FAM47E (HGNC:34343): (family with sequence similarity 47 member E) Enables enzyme activator activity. Involved in positive regulation of histone methylation and protein localization to chromatin. Located in chromatin; cytoplasm; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

FAM47E-STBD1 (HGNC:44667): (FAM47E-STBD1 readthrough) This locus represents naturally occurring read-through transcription between the neighboring FAM47E (family with sequence similarity 47, member E) and STBD1 (starch binding domain 1) genes on chromosome 4. The read-through transcript encodes a protein that shares sequence identity with the upstream gene product but its C-terminal region is distinct due to frameshifts relative to the downstream gene.

ENSG00000287401 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.64).
• BP7: Synonymous conserved (PhyloP=1.19 with no splicing effect.
