    1. and he was placed on regular intravenous immunoglobulin (IVIG) replacement therapy. During follow-up,due to his syndromic physical features, speech delays, and delayed teething, we investigated the underlyinggenetic cause of his agammaglobulinemia. Molecular analysis revealed a rare, novel homozygous variantc.244dup in the PIK3R1 gene. Mutations in this gene have been associated with both SHORT syndrome andautosomal recessive agammaglobulinemia as separate clinical entities. Our patient exhibits clinical andlaboratory findings consistent with both SHORT syndrome and agammaglobulinemia due to this novelmutation

      Case#: male, onset at or before age 12 months, ethnicity not specified DiseaseAssertion: Patient is asserted to have both "SHORT syndrome" and "X-linked agammaglobulinemia (XLA)" due to "absence of peripheral B cells" and "features of SHORT syndrome such as hyperextensibility, vision abnormalities, lack of fat tissue, triangular face, extroverted ears, ocular depression, [and] developmental and teething delay" CasePresentingHPOs: HP:0000974 (Hyperextensible skin), HP:0000504 (Abnormality of vision), HP:0005320 (Lack of facial subcutaneous fat), HP:0000325 (Triangular face), HP:0000430 (Underdeveloped nasal alae), HP:0000490 (Deeply set eye), HP:0000750 (Delayed speech and language development), HP:0002719 (Recurrent infections), HP:0030084 (Clinodactyly), HP:0045075 (Sparse eyebrow), HP:0000540 (Hypermetropia), HP:0000696 (Delayed eruption of permanent teeth) CaseHPOFreeText: A current 9 year old was diagnosed with XLA with SHORT at age 15 months after presenting with skin lesions, scrotal swelling and ulcers along with recurring upper and lower tract infections after 6 months of age. Evaluations for immunodeficiencies were performed. Basic immunoglobulin levels and lymphocyte subsets were measured, which suggested an XLA diagnosis. Delays in developmental milestones observed by the mother and physical examination suggested SHORT syndrome. CaseNotHPOs: HP:0000558 (Rieger anomaly), HP:0000364 (Hearing abnormality) GenotypingMethod: Genotyping was performed by whole exome sequencing, whivh revealed a novel pathogenic homozygous frameshift mutation in the PIK3R1 gene. PreviouslyPublished: No prior article is known to contain information on the same proband. Variant: The patient harbors NM_181523.3:c.244dup(p.(lle82Asnfs24) chr5:67522740) variant in the homozygous state. ClinVar: This variant was not found in ClinVar CAID: This variant was not found in the ClinGen Allele Registry. gnomAD:* The variant was not found in gnomAD v4.1.0.
