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 GeneticsOct 30, 2023The c.412A>G (p.T138A) alteration is located in exon 6 (coding exon 6) of the GCSAM gene. This alteration results from a A to G substitution at nucleotide position 412, causing the threonine (T) at amino acid position 138 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
