Genes affected

CHKA (HGNC:1937): (choline kinase alpha) The major pathway for the biosynthesis of phosphatidylcholine occurs via the CDP-choline pathway. The protein encoded by this gene is the initial enzyme in the sequence and may play a regulatory role. The encoded protein also catalyzes the phosphorylation of ethanolamine. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

CHKA (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.708 is higher than 0.05.
