Genes affected
ARMCX1 (HGNC:18073): (armadillo repeat containing X-linked 1) This gene encodes a member of the ALEX family of proteins and may play a role in tumor suppression. The encoded protein contains a potential N-terminal transmembrane domain and two Armadillo (arm) repeats. Other proteins containing the arm repeat are involved in development, maintenance of tissue integrity, and tumorigenesis. This gene is closely localized with other family members, including ALEX2 and ALEX3, on the X chromosome. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2024The c.968A>G (p.H323R) alteration is located in exon 4 (coding exon 1) of the ARMCX1 gene. This alteration results from a A to G substitution at nucleotide position 968, causing the histidine (H) at amino acid position 323 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
