Genes affected
GCSAM (HGNC:20253): (germinal center associated signaling and motility) This gene encodes a protein which may function in signal transduction pathways and whose expression is elevated in germinal cell lymphomas. It contains a putative PDZ-interacting domain, an immunoreceptor tyrosine-based activation motif (ITAM), and two putative SH2 binding sites. In B cells, its expression is specifically induced by interleukin-4. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
C3orf52 (HGNC:26255): (chromosome 3 open reading frame 52) Predicted to be located in endoplasmic reticulum membrane. Predicted to be 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 GeneticsApr 07, 2022The c.499C>T (p.R167C) alteration is located in exon 6 (coding exon 6) of the GCSAM gene. This alteration results from a C to T substitution at nucleotide position 499, causing the arginine (R) at amino acid position 167 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
