Key Clinical Message Among the total 10 reported cases with 20p13 microdeletion, including our patient, it is notable that 50% of patients presented a height below the 3rd percentile. We suggest that short stature is among the most common manifestations in patients with 20p13 subtelomeric microdeletion. Abstract Chromosome 20p13 microdeletion occurs rarely, with only 10 reported cases. We report a 16‐year‐old male with a 1.59 Mb terminal deletion in chromosome 20p13, who presented with proportionate short stature, mild language delay, mild learning disability, and delayed puberty. The clinical phenotype associated with this deletion can exhibit clinical variability. Our patient deviates from the typical developmental and intellectual phenotype seen in the 20p13 deletion, instead displaying mild speech delay, short stature, and delayed puberty. The CSNK2A1 deletion, leading to haploinsufficiency, might be the potential mechanism. And the prominence of his proportionate short stature provides a unique perspective to review the existing literature. |
