Genes affected

MYL12A (HGNC:16701): (myosin light chain 12A) This gene encodes a nonsarcomeric myosin regulatory light chain. This protein is activated by phosphorylation and regulates smooth muscle and non-muscle cell contraction. This protein may also be involved in DNA damage repair by sequestering the transcriptional regulator apoptosis-antagonizing transcription factor (AATF)/Che-1 which functions as a repressor of p53-driven apoptosis. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 8.[provided by RefSeq, Dec 2014]

MYL12-AS1 (HGNC:55331): (MYL12A and MYL12B antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.72).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.248 is higher than 0.05.
