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]
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 c.187G>A (p.G63S) alteration is located in exon 3 (coding exon 3) of the SLC51A gene. This alteration results from a G to A substitution at nucleotide position 187, causing the glycine (G) at amino acid position 63 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
