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]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.37754792).

Collection Method: clinical testing

The c.1061G>C (p.R354P) alteration is located in exon 9 (coding exon 8) of the SSC4D gene. This alteration results from a G to C substitution at nucleotide position 1061, causing the arginine (R) at amino acid position 354 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
