Genes affected

SCMH1 (HGNC:19003): (Scm polycomb group protein homolog 1) Predicted to enable chromatin binding activity and histone binding activity. Predicted to be involved in negative regulation of transcription, DNA-templated. Predicted to act upstream of or within anterior/posterior pattern specification; chromatin remodeling; and spermatogenesis. Predicted to be located in nucleoplasm. Predicted to be active in nucleus.

The c.973C>G (p.P325A) alteration is located in exon 10 (coding exon 7) of the SCMH1 gene. This alteration results from a C to G substitution at nucleotide position 973, causing the proline (P) at amino acid position 325 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
