Genes affected
HAVCR1 (HGNC:17866): (hepatitis A virus cellular receptor 1) The protein encoded by this gene is a membrane receptor for both human hepatitis A virus (HHAV) and TIMD4. The encoded protein may be involved in the moderation of asthma and allergic diseases. The reference genome represents an allele that retains a MTTVP amino acid segment that confers protection against atopy in HHAV seropositive individuals. The protein is a receptor for multiple other viruses, including Ebola virus, Marburg virus, Dengue virus, and Zika virus and is a possible entry factor for SARS-CoV-2 and other coronaviruses.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2023The c.1002C>A (p.S334R) alteration is located in exon 8 (coding exon 8) of the HAVCR1 gene. This alteration results from a C to A substitution at nucleotide position 1002, causing the serine (S) at amino acid position 334 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
