Genes affected
NFAM1 (HGNC:29872): (NFAT activating protein with ITAM motif 1) The protein encoded by this gene is a type I membrane receptor that activates cytokine gene promoters such as the IL-13 and TNF-alpha promoters. The encoded protein contains an immunoreceptor tyrosine-based activation motif (ITAM) and is thought to regulate the signaling and development of B-cells. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.473C>T (p.P158L) alteration is located in exon 3 (coding exon 3) of the NFAM1 gene. This alteration results from a C to T substitution at nucleotide position 473, causing the proline (P) at amino acid position 158 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
