Genes affected

ZNF674 (HGNC:17625): (zinc finger protein 674) This gene encodes a zinc finger protein with an N-terminal Kruppel-associated box-containing (KRAB) domain and 11 Kruppel-type C2H2 zinc finger domains. Like other zinc finger proteins, this gene may function as a transcription factor. This gene resides on an area of chromosome X that has been implicated in nonsyndromic X-linked cognitive disabilities. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2017]

ACMG classification

Our verdict: Benign. The variant received -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.007127017).
• BP6: Variant X-46500464-A-C is Benign according to our data. Variant chrX-46500464-A-C is described in ClinVar as [Benign]. Clinvar id is 130841.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS2: High Homozygotes in GnomAd4 at 4 XL gene
