Genes affected

ZKSCAN5 (HGNC:12867): (zinc finger with KRAB and SCAN domains 5) This gene encodes a zinc finger protein of the Kruppel family. The protein contains a SCAN box and a KRAB A domain and may be involved in transcriptional regulation. A similar protein in mouse is differentially expressed in spermatogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM1: In a modified_residue Phosphoserine (size 0) in uniprot entity ZKSC5_HUMAN
• BP4: Computational evidence support a benign effect (MetaRNN=0.008966476).

Collection Method: clinical testing

The c.1005C>A (p.S335R) alteration is located in exon 6 (coding exon 5) of the ZKSCAN5 gene. This alteration results from a C to A substitution at nucleotide position 1005, causing the serine (S) at amino acid position 335 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
