Genes affected
MOB4 (HGNC:17261): (MOB family member 4, phocein) This gene was identified based on its similarity with the mouse counterpart. Studies of the mouse counterpart suggest that the expression of this gene may be regulated during oocyte maturation and preimplantation following zygotic gene activation. Alternatively spliced transcript variants encoding distinct isoforms have been observed. Naturally occurring read-through transcription occurs between this locus and the neighboring locus HSPE1.[provided by RefSeq, Feb 2011]
HSPD1 (HGNC:5261): (heat shock protein family D (Hsp60) member 1) This gene encodes a member of the chaperonin family. The encoded mitochondrial protein may function as a signaling molecule in the innate immune system. This protein is essential for the folding and assembly of newly imported proteins in the mitochondria. This gene is adjacent to a related family member and the region between the 2 genes functions as a bidirectional promoter. Several pseudogenes have been associated with this gene. Two transcript variants encoding the same protein have been identified for this gene. Mutations associated with this gene cause autosomal recessive spastic paraplegia 13.

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The c.23C>T (p.A8V) alteration is located in exon 1 (coding exon 1) of the MOB4 gene. This alteration results from a C to T substitution at nucleotide position 23, causing the alanine (A) at amino acid position 8 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
