Genes affected
SECTM1 (HGNC:10707): (secreted and transmembrane 1) This gene encodes a transmembrane and secreted protein with characteristics of a type 1a transmembrane protein. It is found in a perinuclear Golgi-like pattern and thought to be involved in hematopoietic and/or immune system processes. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 06, 2023The c.529C>T (p.R177C) alteration is located in exon 4 (coding exon 3) of the SECTM1 gene. This alteration results from a C to T substitution at nucleotide position 529, causing the arginine (R) at amino acid position 177 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
