Genes affected
BORCS8 (HGNC:37247): (BLOC-1 related complex subunit 8) Involved in heart development. Part of BORC complex. [provided by Alliance of Genome Resources, Apr 2022]
MEF2B (HGNC:6995): (myocyte enhancer factor 2B) The product of this gene is a member of the MADS/MEF2 family of DNA binding proteins. The protein is thought to regulate gene expression, including expression of the smooth muscle myosin heavy chain gene. This region undergoes considerable alternative splicing, with transcripts supporting two non-overlapping loci (GeneID 729991 and 100271849) as well as numerous read-through transcripts that span both loci (annotated as GeneID 4207). Several isoforms of this protein are expressed from either this locus or from some of the read-through transcripts annotated on GeneID 4207. [provided by RefSeq, Jan 2014]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 17, 2021 | The c.119G>A (p.R40H) alteration is located in exon 2 (coding exon 2) of the BORCS8 gene. This alteration results from a G to A substitution at nucleotide position 119, causing the arginine (R) at amino acid position 40 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
