Genes affected

RARRES1 (HGNC:9867): (retinoic acid receptor responder 1) This gene was identified as a retinoid acid (RA) receptor-responsive gene. It encodes a type 1 membrane protein. The expression of this gene is upregulated by tazarotene as well as by retinoic acid receptors. The expression of this gene is found to be downregulated in prostate cancer, which is caused by the methylation of its promoter and CpG island. Alternatively spliced transcript variant encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008]

MFSD1 (HGNC:25874): (major facilitator superfamily domain containing 1) Predicted to enable protein homodimerization activity. Predicted to be involved in protein localization to lysosome and protein stabilization. Predicted to be located in lysosome. [provided by Alliance of Genome Resources, Apr 2022]

The c.250G>A (p.A84T) alteration is located in exon 1 (coding exon 1) of the RARRES1 gene. This alteration results from a G to A substitution at nucleotide position 250, causing the alanine (A) at amino acid position 84 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
