Genes affected

MS4A7 (HGNC:13378): (membrane spanning 4-domains A7) This gene encodes a member of the membrane-spanning 4A gene family, members of which are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns in hematopoietic cells and nonlymphoid tissues. This family member is associated with mature cellular function in the monocytic lineage, and it may be a component of a receptor complex involved in signal transduction. This gene is localized to 11q12, in a cluster of other family members. At least four alternatively spliced transcript variants encoding two distinct isoforms have been observed.

MS4A14 (HGNC:30706): (membrane spanning 4-domains A14) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

MS4A6E (HGNC:14285): (membrane spanning 4-domains A6E) This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. The gene encoding this protein is localized to 11q12.3, among a cluster of family members. [provided by RefSeq, Jul 2008]

The c.518A>T (p.D173V) alteration is located in exon 5 (coding exon 4) of the MS4A7 gene. This alteration results from a A to T substitution at nucleotide position 518, causing the aspartic acid (D) at amino acid position 173 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
