Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2 BP4

The NM_001136570.3(FAM47E):​c.451C>G​(p.Pro151Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P151S) has been classified as Uncertain significance.

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: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.40197086).
