Genes affected
MS4A4A (HGNC:13371): (membrane spanning 4-domains A4A) This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features, similar intron/exon splice boundaries, and display unique expression patterns in hematopoietic cells and nonlymphoid tissues. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.551T>C (p.L184P) alteration is located in exon 6 (coding exon 6) of the MS4A4A gene. This alteration results from a T to C substitution at nucleotide position 551, causing the leucine (L) at amino acid position 184 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
