Genes affected
SLC29A3 (HGNC:23096): (solute carrier family 29 member 3) This gene encodes a nucleoside transporter. The encoded protein plays a role in cellular uptake of nucleosides, nucleobases, and their related analogs. Mutations in this gene have been associated with H syndrome, which is characterized by cutaneous hyperpigmentation and hypertrichosis, hepatosplenomegaly, heart anomalies, and hypogonadism. A related disorder, PHID (pigmented hypertrichosis with insulin-dependent diabetes mellitus), has also been associated with mutations at this locus. Alternatively spliced transcript variants have been described.[provided by RefSeq, Mar 2010]

H syndrome Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 28, 2017For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in SLC29A3 are known to be pathogenic (PMID: 19336477, 20595384, 23406517, 25963354). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with SLC29A3-related disease. This variant is present in population databases (rs776960135, ExAC 0.009%). This sequence change creates a premature translational stop signal (p.Trp160*) in the SLC29A3 gene. It is expected to result in an absent or disrupted protein product. -
