Genes affected
LILRA1 (HGNC:6602): (leukocyte immunoglobulin like receptor A1) This gene encodes an activating member of the leukocyte immunoglobulin-like receptor (LIR) family, which is found in a gene cluster at chromosomal region 19q13.4. The encoded protein is predominantly expressed in B cells, interacts with major histocompatibility complex class I ligands, and contributes to the regulation of immune responses. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 17, 2024The c.17C>A (p.T6K) alteration is located in exon 2 (coding exon 1) of the LILRA1 gene. This alteration results from a C to A substitution at nucleotide position 17, causing the threonine (T) at amino acid position 6 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
