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.

The c.385C>T (p.L129F) alteration is located in exon 2 (coding exon 2) of the FAM47E gene. This alteration results from a C to T substitution at nucleotide position 385, causing the leucine (L) at amino acid position 129 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
