CasePresentingHPOsFreeText: Broad ribs with sclerosis. Pelvis, peripheral sclerosis. Diaphyseal relative hypodensity. Painless, episodic erythematous papules usually on lower abdomen, legs, or arms. Serum BAP, osteocalcin, and TRACP-5b levels all were consistently low. Maxillary and ethmoid sinuses were opaque at ages 22 and 33 months, and the mastoid air cells were small. Increased amounts of cartilage, decreased hematopoietic marrow, and an absence of identifiable osteoclasts.

CaseNOTHPOSFreeText: Abnormal serum glucose level. Bony tenderness.
CasePreviousTesting: Candidate gene sequencing. No notable variants int CLCN7, TCIRG1, or OSTM1. PCR and sequencing in both directions of all coding exons and adjacent mRNA splice sites of TNFRSF11A, TNFRSF11B, CSF1, CSF1R, and ANKH revealed no mutations. (c.107C > G, p.Pro36Arg) was found in TNFSF11, but not thought to be causal. Microarray-based genomic copy-number analysis of the patient and parents also was unrevealing.
CaseGenotypingMethod: WES
Variant: p.Ser203Pro (c.607T>C) and p.Arg386Gln (c.1157G>A)
ClinVarID: or CAID: CA130662; CA130660
gnomAD: The missense variant Ser203Pro is present in gnomAD v4.0.0 with a MAF=0.00002989 (1/33454 alleles) in the African/African American population and 0 homozygotes.
The missense variant Arg386Gln is present in gnomAD v4.0.0 with a MAF=0.00003999 (3/75018 alleles) in the African/African American population and 0 homozygotes.
AddCaseInfo: Heteroygous, non-consanguineous parents. Father is of Turkish ancestry. The mother's family emigrated to Turkey from Greece 70 years ago. Proband has two healthy brothers. No family history of skeletal disease
