Genes affected
GCSAML (HGNC:29583): (germinal center associated signaling and motility like) This gene encodes a protein thought to be a signaling molecule associated with germinal centers, the sites of proliferation and differentiation of mature B lymphocytes. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 09, 2022The c.71C>T (p.P24L) alteration is located in exon 2 (coding exon 2) of the GCSAML gene. This alteration results from a C to T substitution at nucleotide position 71, causing the proline (P) at amino acid position 24 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
