Genes affected

SLC51A (HGNC:29955): (solute carrier family 51 member A) Predicted to enable protein heterodimerization activity; protein homodimerization activity; and transmembrane transporter activity. Involved in bile acid secretion. Located in basolateral plasma membrane. Implicated in progressive familial intrahepatic cholestasis. [provided by Alliance of Genome Resources, Apr 2022]

SLC51A links:

PCYT1A (HGNC:8754): (phosphate cytidylyltransferase 1A, choline) This gene belongs to the cytidylyltransferase family and is involved in the regulation of phosphatidylcholine biosynthesis. Mutations in this gene are associated with spondylometaphyseal dysplasia with cone-rod dystrophy. Alternatively spliced transcript variants have been found for this gene.

The SLC51A c.420G>T variant is not predicted to result in an amino acid change (p.=). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.11% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-195955043-G-T). This variant is synonymous, however cryptic donor splice site is predicted with some probability (Alamut Visual Plus v1.6.1). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
