Genes affected

SLC12A4 (HGNC:10913): (solute carrier family 12 member 4) This gene encodes a member of the SLC12A transporter family. The encoded protein mediates the coupled movement of potassium and chloride ions across the plasma membrane. This gene is expressed ubiquitously. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jan 2013]

LCAT (HGNC:6522): (lecithin-cholesterol acyltransferase) This gene encodes the extracellular cholesterol esterifying enzyme, lecithin-cholesterol acyltransferase. The esterification of cholesterol is required for cholesterol transport. Mutations in this gene have been found to cause fish-eye disease as well as LCAT deficiency. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP6: Variant 16-67943479-T-C is Benign according to our data. Variant chr16-67943479-T-C is described in ClinVar as [Benign]. Clinvar id is 1221653.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr16-67943479-T-C is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.646 is higher than 0.05.
