Genes affected

NOBOX (HGNC:22448): (NOBOX oogenesis homeobox) This homeobox gene encodes a transcription factor that is thought to play a role in oogenesis. In mice, it is essential for folliculogenesis and regulation of oocyte-specific genes. Defects in this gene result in premature ovarian failure type 5.[provided by RefSeq, May 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
• PP5: Variant 7-144399863-C-A is Pathogenic according to our data. Variant chr7-144399863-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 167877.Status of the report is no_assertion_criteria_provided, 0 stars.
