Genes affected

SSC4D (HGNC:14461): (scavenger receptor cysteine rich family member with 4 domains) The scavenger receptor cysteine-rich (SRCR) superfamily is an ancient and highly conserved group of cell surface and/or secreted proteins, some of which are involved in the development of the immune system and the regulation of both innate and adaptive immune responses. Group B SRCR domains usually contain 8 regularly spaced cysteines that give rise to a well-defined intradomain disulfide-bond pattern.[supplied by OMIM, Apr 2004]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1000G>A (p.A334T) alteration is located in exon 8 (coding exon 7) of the SSC4D gene. This alteration results from a G to A substitution at nucleotide position 1000, causing the alanine (A) at amino acid position 334 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
