Genes affected
LAX1 (HGNC:26005): (lymphocyte transmembrane adaptor 1) Enables SH2 domain binding activity and protein kinase binding activity. Involved in several processes, including B cell activation; negative regulation of MAP kinase activity; and negative regulation of T cell activation. Located in Golgi apparatus; cytosol; and plasma membrane. Is integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.812T>C (p.M271T) alteration is located in exon 5 (coding exon 5) of the LAX1 gene. This alteration results from a T to C substitution at nucleotide position 812, causing the methionine (M) at amino acid position 271 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
