This region corresponds to exons 2\u20136 of the short-stature homeobox-containing (<jats:italic>SHOX<\/jats:italic>) gene (NM000451). Associated diseases involving the <jats:italic>SHOX<\/jats:italic> gene range from severe Leri\u2013Weill dyschondrosteosis to mild nonspecific short stature. Meanwhile, further validation using a quantitative reverse transcription polymerase chain reaction assay confirmed the heterozygous deletion of the <jats:italic>SHOX<\/jats:italic> gene in the proband, as well as other family members with similar clinical characteristics (the proband\u2019s mother, aunt, and cousin). Multiple pathogenic reports of this variant have been included in the HGMD database. Per the American College of Medical Genetics and Genomics (ACMG) classification criteria, this deletion is classified as pathogenic. (2) For the male patient, a heterozygous variant was detected in the <jats:italic>CRYBB3<\/jats:italic> gene: NM004076: c.226G&amp;gt;A (p.Gly76R). Variants in the <jats:italic>CRYBB3<\/jats:italic> gene can cause Cataract 22 (OMIM: 609741). At present, this variant locus is not included in databases such as the gnomAD, while both SIFT and PolyPhen2 deem this locus \u2018damaging\u2019. Moreover, further validation by Sanger sequencing confirmed that the variant was inherited from the male patient\u2019s mother, who also had cataracts. According to ACMG standards and guidelines, the c.226G&amp;gt;A (p.Gly76Arg) variant in the <jats:italic>CRYBB3<\/jats:italic> gene is classified as having \u2018uncertain significance\u2019.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>WES identified pathogenic variants in both individuals, suggesting a 25% chance of a healthy child naturally.
