His birth length and weight were 48.4 cm (−0.29 SD) and 2.81 kg (−0.42 SD), respectively. Short stature was noted at 15 months of age; at 18 months, he could not stand alone and motor delay was suspected. He was referred to our hospital at 23 months with length and weight of 79.0 cm (−2.2 SD) and 10.5 kg (−0.82 SD), respectively. He could walk with aid and speak meaning words. Physical examination showed a doll-like appearance, abdominal distension, and hepatomegaly. Laboratory examinations showed as follows: white blood cells, 8800/μL (neutrophils 1584/μL); aspartate aminotransferase, 899 U/L; alanine aminotransferase, 554 U/L; creatine kinase 60 U/L; alkaline phosphatase 966 U/L (age matched reference, 395–1339); γ-glutamyl transpeptidase 374 U/L (reference, 6.5–60.0); creatinine, 0.13 mg/dL; uric acid, 7.0 mg/dL. Fasting glucagon loading test showed glucose of 42 mg/dL (before loading) and 64 mg/dL (60 min after loading). Two-hour postprandial glucagon loading test showed glucose of 131 mg/dL (before loading) and 191 mg/dL (30 min after loading). Oral glucose tolerance tests showed basal lactate and pyruvate levels of 7.0 and 0.61 mg/dL, respectively, and peak lactate and pyruvate levels of 32.2 mg/dL (90 min after loading) and 3.03 mg/dL (30 min after loading), respectively. Computed tomography showed hepatomegaly with high density. Phosphorylase kinase enzyme analysis of red blood cells revealed 0.3 nmoL/min/gHb, compared to 9.1 and 10.1 nmoL/min/gHb in two healthy subjects. We thus diagnosed him as having GSD IXa. After obtaining informed consent from his parents, genomic DNA was extracted from peripheral blood samples of the proband and his mother. We tried to amplify all exons and the flanking introns of the exons in <i>PHKA2</i> (NM_000292.3) in the proband, but we obtained no polymerase chain reaction (PCR) products of exons 20 and 21. We designed several new forward primers located at the intron intervening exons 19 and 20 and the reverse primer located at exon 22. Using these primers, we performed PCR using DNA from the proband or his mother and obtained the products, with the size at 500–650 bp from the proband and 3000 bp and 500–650 bp from his mother (Figure 1A).

Fourteen embryos between Carnegie stage (CS)18 and CS23 and 59 fetuses (crown-rump length: 39.5–185.0 mm) were selected for this study. The PM was first detected in one of the three samples at CS20. It was detected in five of the seven samples (71.4%) between CS21 and CS23. Forty-eight samples (81.4%) at early fetal period had PMs on both the right and left sides, and 3 (5.1%) had it only on the right side. Eight samples (13.6%) had no PMs. No side-differences or sexual dimorphisms were detected. The PM length was larger than the width in most samples, although the length/width ratio varied among the samples. The PM/rectus abdominis muscle length and PM/umbilicus-pubic symphysis length ratios were almost constant, irrespective of the crown-rump length. The PM was located ventrally inferior to the rectus abdominis and closer to the medial muscle groups of the lower limb than the rectus abdominis.

In this study, we investigated the status of the accumulation of JDIIP consultation cases to identify issues for enhancing clinical information appropriate for use during pregnancy and to examine how information should be collected and provided. In addition, the status of descriptions of Japanese package inserts, which are representative of those used by healthcare professionals as a source of information, was confirmed for medications used by JDIIP consultation cases. The characteristics of the JDIIP consultation cases information were that the contents that needed to be adjusted when evaluating the effects on the fetus of medication use during pregnancy were obtained.

However, although the number of consultation facilities has increased, the number of consultations has not, indicating the need to further increase the number.
