However, analysing <i>Sema3A</i> and <i>Sema7A</i> SNPs with clinical manifestations of SLE indicated that, in <i>Sema3A</i>, the A allele frequencies of rs7804122 polymorphism was higher in patients with oral ulcers.
By analyzing protein expression and processing, we did not observe any differences of the p.I668V variant compared with wild-type SEMA3A, while a pathogenic SEMA3A variant p.R66W recently described in a patient with Kallmann syndrome did affect protein secretion.
Under the linear regression model, rs139438618 at the semaphorin 3A (SEMA3A [OMIM 603961]) locus was significantly associated with AD and MD comorbidity in African American participants in the Yale-Penn 1 sample (β = 0.89; 95% CI, 0.57-1.20; P = 2.76 × 10-8).
Two novel heterozygous missense mutations in FGFR1, (NM_001174066): c.776G>A (p.G259E) and (NM_001174066): c.358C>T (p.R120C), were identified in a 23-year-old KS male with cleft lip and an 18-year-old KS patient with cleft lip and palate, dental agenesis, and high arched palate, respectively.

Three heterozygous variants (c.458A>G (p.Asn153Ser), c.1253A>G (p.Asn418Ser), and c.1303G>A (p.Val435Ile)) were found in SEMA3A in three KS patients, two of which also had a mutation in FGFR1.
A high incidence of SEMA3A(I334V) in UCA patients and inappropriate innervation patterning in their hearts implicate involvement of the SEMA3A gene in the pathogenesis of UCA.
Our results for rs7804122 provided preliminary evidence that the SEMA3A gene is involved in the susceptibility to HSCR in the Northeastern Chinese population.
The genotypes of two SNPs (rs7804122 and rs797821) in the SEMA3A gene in 119 patients with HSCR and 93 controls were examined using PCR-sequencing to determine the contribution of SEMA3A to the HSCR phenotype.
