Genes affected
IL34 (HGNC:28529): (interleukin 34) Interleukin-34 is a cytokine that promotes the differentiation and viability of monocytes and macrophages through the colony-stimulating factor-1 receptor (CSF1R; MIM 164770) (Lin et al., 2008 [PubMed 18467591]).[supplied by OMIM, May 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.646C>T (p.P216S) alteration is located in exon 7 (coding exon 6) of the IL34 gene. This alteration results from a C to T substitution at nucleotide position 646, causing the proline (P) at amino acid position 216 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
