BACKGROUND Spinal muscular atrophy (SMA) is a neuromuscular disease mainly caused by the absence of both copies of the survival motor neuron 1 (SMN1) gene. Multiple regions recommended population-wide SMA screening to quantify the copy number of SMN1. SMN1 diagnostic assays for the simplified procedure, high sensitivity, and throughput continue to be needed. METHODS Real-time PCR with high-resolution melting for the quantifying of the SMN1 gene exon 7 copies and exon 8 copies were established and confirmed by multiplex ligation-dependent probe amplification (MLPA). The diagnosis of 2563 individuals, including SMA patients, suspected cases, and the general population, was tested by real-time PCR. The results were compared with the gold standard test MLPA. RESULTS In this study, the homozygous and heterozygous deletions were detected by real-time PCR with a high-resolution melting method with an incidence of 10.18% and 2.26%, respectively. In addition, the R-value distribution (P > 0.05) among 8 replicates and the coefficient of variation (CV < 0.003) suggested that the real-time PCR screening test had high reproducibility. High concordance was obtained between real-time PCR with high-resolution melting and MLPA. CONCLUSIONS The real-time PCR based on high-resolution melting provides a sensitive and high-throughput approach to large-scale SMA carrier screening with low cost and labor.

BACKGROUND PURA-related neurodevelopmental disorders (PURA-NDDs) include 5q31.3 deletion syndrome and PURA syndrome. PURA-NDDs are characterized by neonatal hypotonia, moderate to severe global developmental delay/intellectual disability (GDD/ID), facial dysmorphism, epileptic seizures, nonepileptic movement disorders, and ophthalmological problems. PURA-NDDs have recently been identified and underestimated in neurodevelopmental cohorts, but their diagnosis is still challenging. METHODS We retrospectively reviewed the clinical characteristics, genetic spectrum, and diagnostic journey of patients with PURA-NDDs. RESULTS We report 2 patients with 5q31.3 microdeletion and 5 with PURA pathogenic variants. They demonstrated hypotonia (7/7, 100%), feeding difficulties (4/5, 80%), and respiratory problems (4/7, 57%) in the neonatal period. All of them had severe GDD/ID and could not achieve independent walking and verbal responses. Distinctive facial features of open-tented upper vermilion, long philtrum, and anteverted nares and poor visual fixation and tracking with or without nystagmus were most commonly found (5/7, 71.4%). There were no significant differences in clinical phenotypes between 5q31.3 microdeletion syndrome and PURA syndrome. PURA-NDDs need to be considered as a differential diagnosis in individuals who show severe hypotonia, including feeding difficulties since birth and severe developmental retardation with distinctive facial and ophthalmological features. CONCLUSIONS Our data expands the phenotypic and genetic spectrum of PURA-NDD. Next-generation sequencing methods based on the detailed phenotypic evaluation would shorten the diagnostic delay and would help this rare disorder become a recognizable cause of neurodevelopmental delay.
