Variant names:

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_152672.6(SLC51A):c.134C>A(p.Ala45Asp) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000372 in 1,611,974 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/24 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. A45A) has been classified as Likely benign.

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. [provided by RefSeq, Aug 2015]
