PARVB and premenstrual tension: Genotype–phenotype correlations confirmed haploinsufficiency of the SHANK3 gene for PMS and suggested other candidate haploinsufficient genes TNFRSFI3C and NFAM1 genes for immunological features and TCF20, SULT4A1, PARVB, SCO2, and UPK3A genes for intellectual impairment and behavioral abnormality, neurological features, macrocephaly/hypotonia, oculopathy, and renal adysplasia, respectively.
